pnpm: patch-remove could delete project-selected files outside the patches directory

GHSA-72r4-9c5j-mj57

More information

Details

Summary

The patch-remove deletion-scope issue tracked as GHSA-72r4-9c5j-mj57 / CAND-PNPM-030 has been addressed in pnpm.

A crafted patch entry could resolve outside the configured patches directory and cause pnpm patch-remove to delete an arbitrary reachable file. This patch validates the configured directory and every resolved target before unlinking anything, then deletes the final directory entry without following it.

Security boundary

• Traversal and absolute paths that resolve outside the configured patches directory are rejected before deletion.
• Parent directories are canonicalized before deletion, including the case where a nested symlink points outside and the final outside entry is itself dangling.
• The complete batch is validated before any file is removed.
• Component-aware predicates accept valid names beginning with .. while still rejecting parent traversal, Windows drive escapes, and UNC escapes.
• Valid files and symlinked patch directories whose canonical targets remain below the lockfile directory continue to work.
• A final symlink inside a valid patch directory is unlinked without following its target, including when the target is outside or dangling.

Exploit replay

Before the patch, a workspace patchedDependencies path that resolved outside the project caused pnpm patch-remove to delete the external sentinel. A second replay used a nested parent symlink and a dangling outside victim: realpath() returned ENOENT, yet the victim was still removed. With this patch, both paths are rejected and the outside entries remain intact.

Files changed

• patching/commands/src/isSubdirectory.ts performs component-aware containment checks.
• patching/commands/src/patchRemove.ts validates the full batch, canonicalizes parents, and unlinks final entries without following them.
• patching/commands/test/{isSubdirectory,patchRemove}.test.ts covers traversal, nested symlinks, dangling victims, and valid removals.

Commands run

$ pnpm --filter @​pnpm/patching.commands test test/isSubdirectory.test.ts test/patchRemove.test.ts
PASS: 11 tests across 2 suites
$ pnpm --filter @​pnpm/patching.commands run compile
PASS
$ git diff --check
PASS

Validation

• Focused handler and path-predicate suites: 11 passed across 2 suites.
• Package-wide ESLint: passed.
• Package TypeScript build: passed.
• Commit hooks, Commitlint, and git diff --check: passed.
• The broader integration harness was environment-blocked because it writes outside the available temporary root; focused handler tests used /private/tmp.

Patches

10.34.4: pnpm/pnpm@352ae48
11.7.0: pnpm/pnpm@612a2e6

Compatibility

Missing patch files remain no-ops. Valid symlinked patch directories continue to work when their canonical target stays inside the lockfile directory, and final symlinks are removed without touching their targets. patch-remove is not yet in pacquet's command surface, so no Rust-side parity change is required.

Remaining risk

Portable Node APIs do not expose directory-fd-relative unlinkat(). A local attacker who can replace an already validated parent directory before the unlink may still win a time-of-check/time-of-use race. The reproduced repository-controlled traversal and symlink paths do not require that concurrent capability and are blocked by this patch.

pnpm: Hoisted install imports lockfile alias outside node_modules

GHSA-fr4h-3cph-29xv

More information

Details

Summary

The hoisted dependency alias issue tracked as GHSA-fr4h-3cph-29xv / CAND-PNPM-059 has been addressed in both pnpm and pacquet.

A crafted lockfile alias could be joined directly under a hoisted node_modules directory. Traversal aliases could escape that directory, while reserved aliases such as .bin or .pnpm could overwrite pnpm-owned layout. This patch validates package-name semantics and path containment before graph insertion or filesystem work.

Security boundary

• The TypeScript hoisted graph uses the shared safe join helper at the actual dep.name sink.
• The helper rejects traversal, absolute, platform-specific, and reserved package names.
• Pacquet validates the hoister's dep.0.name before adding the graph node or recursing.
• Both implementations return ERR_PNPM_INVALID_DEPENDENCY_NAME.
• Pacquet uses the same dependency-name containment rule at its hoisted graph sink as it uses for direct dependency aliases.

Exploit replay

Before the patch, a traversal alias in a hoisted lockfile imported package files outside the intended install root. With this patch, both pnpm and pacquet reject the alias before graph insertion or filesystem work, and the escaped file is not created.

Files changed

• fs/symlink-dependency/src/safeJoinModulesDir.ts provides the TypeScript containment helper.
• installing/deps-restorer/src/lockfileToHoistedDepGraph.ts validates the parsed dependency name at the hoisted graph sink.
• pacquet/crates/package-manager/src/{hoisted_dep_graph.rs,safe_join_modules_dir.rs} mirrors that boundary in Rust.
• TypeScript and Rust tests cover traversal, reserved aliases, and valid scoped names.

Commands run

$ pnpm --filter @​pnpm/fs.symlink-dependency test
PASS: 24 tests
$ pnpm --filter @​pnpm/installing.deps-restorer test test/index.ts
PASS: exploit regression and positive install control
$ cargo test --locked -p pacquet-package-manager --lib
PASS: 426 tests
$ cargo fmt --all -- --check
PASS

Validation

• TypeScript symlink helper: 24 passed.
• TypeScript exploit regression: 1 passed.
• TypeScript positive hoisted-install control: 1 passed.
• Targeted strict TypeScript compiles: passed.
• Targeted ESLint: zero errors.
• Pacquet helper tests: 3 passed.
• Full pacquet package-manager library suite: 426 passed.

pnpm: Path traversal in configDependencies env lockfile allows symlink creation outside node_modules/.pnpm-config

GHSA-qrv3-253h-g69c

More information

Details

Summary

pnpm accepts package names from the env lockfile configDependencies section and uses those names directly when creating config dependency symlinks under node_modules/.pnpm-config.

A malicious repository can commit a crafted pnpm-lock.yaml whose env-lockfile document contains a traversal-shaped config dependency name such as ../../PWNED_CFGDEP. During pnpm install, pnpm installs the config dependency and creates a symlink at a path derived from that name.

In local testing against pnpm v11.5.1, this caused pnpm to create a symlink outside the intended config dependency directory:

expected root: /tmp/pnpm-cfgdep-poc-sznwgunx/victim/node_modules/.pnpm-config
actual path:   /tmp/pnpm-cfgdep-poc-sznwgunx/victim/PWNED_CFGDEP

This works with --ignore-scripts, so it does not rely on lifecycle script execution.

Vulnerable behavior

The vulnerable behavior appears to be that configDependencies keys from the env lockfile are trusted as package names and used in filesystem paths without rejecting traversal components.

The relevant pattern is:

const configModulesDir = path.join(opts.rootDir, 'node_modules/.pnpm-config')

for (const [pkgName, pkg] of Object.entries(normalizedDeps)) {
  const configDepPath = path.join(configModulesDir, pkgName)

  const pkgDirInGlobalVirtualStore = path.join(
    globalVirtualStoreDir,
    relPath,
    'node_modules',
    pkgName
  )

  await symlinkDir(pkgDirInGlobalVirtualStore, configDepPath)
}

If pkgName is attacker-controlled and contains .., then path.join(configModulesDir, pkgName) can resolve outside node_modules/.pnpm-config.

Impact

A malicious project can cause pnpm to create symlinks outside the intended node_modules/.pnpm-config directory during install.

This gives an attacker a filesystem write primitive in the victim project directory, and potentially outside it with deeper traversal payloads, depending on path permissions and platform behavior.

The issue is especially relevant because:

• The malicious input is committed in pnpm-lock.yaml.
• The issue is triggered during pnpm install.
• It works with --ignore-scripts.
• It occurs in the config dependency installation path, before ordinary dependency installation.
• The user only needs to install a malicious or compromised repository.

Local proof of concept

The following local-only PoC creates a temporary project, starts a local fake registry on 127.0.0.1, writes a malicious env-lockfile entry, runs pnpm, and checks whether pnpm created a symlink outside node_modules/.pnpm-config.

Command used:

python3 ../pnpm_configdeps_path_traversal_poc.py \
  --pnpm-cmd "node /home/ethical/pnpm-main/pnpm/bin/pnpm.cjs" \
  --keep 2>&1 | tee /tmp/pnpm-configdeps-poc.log

Observed output:

[+] Test project:       /tmp/pnpm-cfgdep-poc-sznwgunx/victim
[+] Local registry:     http://127.0.0.1:36545/
[+] Store dir:          /tmp/pnpm-cfgdep-poc-sznwgunx/store
[+] Malicious name:     '../../PWNED_CFGDEP'
[+] Intended cfg root:  /tmp/pnpm-cfgdep-poc-sznwgunx/victim/node_modules/.pnpm-config
[+] Traversal sink:     /tmp/pnpm-cfgdep-poc-sznwgunx/victim/PWNED_CFGDEP
[+] Lockfile written:   /tmp/pnpm-cfgdep-poc-sznwgunx/victim/pnpm-lock.yaml
[+] Running: node /home/ethical/pnpm-main/pnpm/bin/pnpm.cjs install --ignore-scripts --config.confirmModulesPurge=false --reporter=append-only --store-dir /tmp/pnpm-cfgdep-poc-sznwgunx/store --registry http://127.0.0.1:36545/

pnpm output:

Installing config dependencies...
Installed config dependencies: ../../PWNED_CFGDEP@1.0.0, legit-config-dep@1.0.0
Already up to date

Done in 906ms using pnpm v11.5.1

The PoC then detected the escaped symlink:

[+] Traversal sink status: symlink -> ../store/v11/PWNED_CFGDEP/1.0.0/PWNED_CFGDEP

[VULNERABLE] pnpm created/modified a path derived from a lockfile package name outside node_modules/.pnpm-config
            sink = /tmp/pnpm-cfgdep-poc-sznwgunx/victim/PWNED_CFGDEP
            readlink = ../store/v11/PWNED_CFGDEP/1.0.0/PWNED_CFGDEP

Malicious lockfile structure

The malicious input is an env-lockfile configDependencies key containing traversal components:

importers:
  .:
    configDependencies:
      legit-config-dep:
        specifier: '1.0.0'
        version: '1.0.0'
      '../../PWNED_CFGDEP':
        specifier: '1.0.0'
        version: '1.0.0'

pnpm accepts the traversal-shaped name and reports it as installed:

Installed config dependencies: ../../PWNED_CFGDEP@1.0.0, legit-config-dep@1.0.0

Security boundary violation

The intended config dependency root was:

/tmp/pnpm-cfgdep-poc-sznwgunx/victim/node_modules/.pnpm-config

But pnpm created:

/tmp/pnpm-cfgdep-poc-sznwgunx/victim/PWNED_CFGDEP

This demonstrates that a config dependency name from the lockfile can escape the directory where config dependencies should be linked.

Suggested remediation

Validate every configDependencies key loaded from the env lockfile before using it as a package name or path component.

Recommended fixes:

1. Reject env-lockfile configDependencies names that are not valid npm package names.

2. Reject names containing absolute paths, . components, .. components, backslashes, or platform-specific path separators.

3. Use containment-checked path joining before creating symlinks:

   • resolve the final destination path,
   • verify it remains inside node_modules/.pnpm-config,
   • reject if it escapes.

4. Apply the same validation to config dependency subdependencies and optional dependency names read from the env lockfile.

5. Intersect env-lockfile configDependencies with the effective pnpm-workspace.yaml configDependencies before installing, so extra lockfile-only entries are rejected.

A safe destination check should enforce behavior equivalent to:

const dest = path.resolve(configModulesDir, pkgName)

if (!dest.startsWith(path.resolve(configModulesDir) + path.sep)) {
  throw new Error(`Invalid config dependency name: ${pkgName}`)
}

Name validation should happen before this check, not instead of it.

The full patched replay for the shared branch passed with all 20 candidates marked fixed. This candidate's replay evidence is results/CAND-PNPM-097-patched-result.json.

Summary

pnpm can install configDependencies declared in pnpm-workspace.yaml before command dispatch. Before the patch, a repository could declare pacquet or @pnpm/pacquet as a config dependency and pnpm treated that repository-controlled dependency as an install-engine opt-in. During install, pnpm resolved a platform-specific @pacquet/<platform>-<arch>/pacquet binary from node_modules/.pnpm-config/<packageName> and spawned it as the developer or CI user.

Details

The vulnerable source-to-sink path was:

• config/reader/src/getOptionsFromRootManifest.ts copies repository pnpm-workspace.yaml configDependencies into config.
• pnpm/src/getConfig.ts installs config dependencies before command dispatch.
• installing/env-installer/src/resolveAndInstallConfigDeps.ts resolves the repository-declared dependency and its optional platform subdependencies.
• installing/env-installer/src/installConfigDeps.ts fetches, imports, and symlinks the config dependency tree under node_modules/.pnpm-config.
• installing/commands/src/installDeps.ts selected pacquet delegation whenever configDependencies contained pacquet or @pnpm/pacquet.
• installing/deps-installer/src/install/index.ts called opts.runPacquet from frozen and materialization paths.
• installing/commands/src/runPacquet.ts resolved @pacquet/${process.platform}-${process.arch}/pacquet from the installed config dependency package and executed it with spawn().

Exact-version, integrity, and platform filters only proved which bytes package resolution selected; they did not establish that the repository was trusted to choose a native install engine.

PoC

Standalone PoC and verification script:

Repository fixture:

packages:
  - .
configDependencies:
  pacquet: 0.2.2

Registry package shape:

{
  "name": "pacquet",
  "version": "0.2.2",
  "optionalDependencies": {
    "@​pacquet/darwin-arm64": "0.2.2"
  }
}

Platform package payload:

#!/bin/sh
echo "$PWD" > /tmp/pacquet-engine-ran
env > /tmp/pacquet-engine-env

Pre-patch exploit model:

1. The victim runs a dependency-management command such as pnpm install in the repository.
2. pnpm installs the repository-declared config dependency and its host-compatible optional platform dependency into .pnpm-config.
3. installDeps() treats the presence of configDependencies.pacquet or configDependencies["@​pnpm/pacquet"] as authorization to delegate install materialization.
4. runPacquet() resolves the platform binary from the installed config dependency tree and spawns it in the lockfile directory.

Observed PoC output:

  "primitive": "repository-selected pacquet config dependency reaches native process execution when selected",
  "patchedWithoutAllowlist": "blocked",
  "trustedAllowlist": "allows explicit opt-in"
}

Validation result:

• The PoC confirmed a selected pacquet config dependency reaches native process execution.
• Patched getPacquetConfigDependencyName() returns undefined without a trusted allowlist.
• Patched getPacquetConfigDependencyName() allows exact pacquet, exact @pnpm/pacquet, and wildcard * trusted opt-in.
• Config reader regressions prove user/global config can set configDependencyInstallEngineAllowlist, while pnpm-workspace.yaml cannot grant this permission to itself.
• E2E fixtures that intentionally delegate to pacquet now pass the trusted allowlist through environment config.
• TypeScript builds passed for @pnpm/config.reader, @pnpm/installing.commands, and pnpm.
• Focused installing/commands/test/runPacquet.ts: 3 passed.
• Focused config/reader/test/index.ts: 2 passed, 132 skipped under the focused pattern.
• ESLint passed with warnings only for existing skipped tests in config/reader/test/index.ts and pnpm/test/install/pacquet.ts.
• git diff --check: passed.

Impact

A malicious repository can cause pnpm to execute a registry-selected native binary while handling dependency-management commands. The binary runs with the victim developer or CI user's filesystem, environment, registry credentials, git/SSH credentials, and network access.

Affected products

Ecosystem: npm

Package name: pnpm, @pnpm/config.reader, @pnpm/installing.commands

Affected versions: current main before this patch, when configDependencies contains pacquet or @pnpm/pacquet and install paths delegate to pacquet.

Patched versions: 10.34.2, 11.5.3.

Severity

Severity: High

Vector string: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Base score: 8.8

Rationale: attacker input is delivered through a repository and registry package, exploitation is low complexity once the victim runs pnpm, no attacker privileges are required, and user interaction is required. Successful exploitation executes a native binary in the victim user's context, with high confidentiality, integrity, and availability impact.

Weaknesses

CWE-829: Inclusion of Functionality from Untrusted Control Sphere

CWE-78: Improper Neutralization of Special Elements used in an OS Command

CWE-494: Download of Code Without Integrity Check

Patch

The patch adds a trusted opt-in gate for config-dependency install-engine delegation:

• New setting: configDependencyInstallEngineAllowlist.
• The allowlist can be set from trusted user-controlled config such as global config, CLI config, or environment config.
• pnpm-workspace.yaml cannot grant this permission to itself; workspace-provided values are discarded after workspace settings are merged.
• installDeps() delegates to pacquet only when pacquet, @pnpm/pacquet, or * is present in the trusted allowlist.
• Repositories can still install pacquet as a config dependency, but pnpm will not spawn it as an install engine unless trusted config opts in.
• Existing tests that intentionally exercise pacquet delegation were updated to pass the trusted allowlist via environment config.

Changed files:

• config/reader/src/Config.ts
• config/reader/src/types.ts
• config/reader/src/configFileKey.ts
• config/reader/src/index.ts
• config/reader/test/index.ts
• installing/commands/src/installDeps.ts
• installing/commands/test/runPacquet.ts
• pnpm/test/install/pacquet.ts

Changeset:

• .changeset/lucky-config-plugin-pnpmfiles.md

Pacquet parity:

No pacquet-side code-execution sink exists for this finding. The Rust port parses and records configDependencies for workspace-state compatibility, but it does not install config dependencies or select/spawn an alternate install engine from them. The user-visible trust setting is TypeScript-side today because it gates pnpm's pacquet delegation path.

CVSS Reassessment

Initial CVSS remains correct for vulnerable versions: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H / 8.8 High.

Final CVSS after patch: not vulnerable after patch / 0.0. The PoC no longer reaches pacquet install-engine selection or native process execution unless the victim has set a trusted allowlist outside the repository's own workspace settings.

Remaining Risk

Users can explicitly trust pacquet install-engine delegation through the new allowlist. That is intentional behavior; the closed issue is repository self-authorization of a registry-provided native install engine.

Release Notes

pnpm/pnpm (pnpm)

v11.5.3: pnpm 11.5.3

Compare Source

⚠️ Security fix — environment variables in a project .npmrc (action may be required)

Following GHSA-3qhv-2rgh-x77r, pnpm no longer expands ${ENV_VAR} placeholders that come from a repository-controlled config file, because a malicious repository could otherwise use them to leak your environment secrets (npm tokens, CI job tokens, etc.) to an attacker-controlled registry during install. This applies to:

• the project/workspace .npmrc — registry, @scope:registry, proxy URLs, URL-scoped keys (//host/…), and credential values (_authToken, _auth, _password, username, tokenHelper, cert, key);
• registry URLs in pnpm-workspace.yaml.

Environment variables are still expanded in trusted config: your user-level ~/.npmrc, the global config, CLI options, and environment config.

If your authentication broke after upgrading, move the token out of the committed .npmrc:

# Writes to your user/global config, not the repository:
pnpm config set "//registry.npmjs.org/:_authToken" "$NPM_TOKEN"

Or keep the ${NPM_TOKEN} line but put it in your user-level ~/.npmrc instead of the repo. In GitHub Actions, actions/setup-node with registry-url already writes a user-level .npmrc, so NODE_AUTH_TOKEN keeps working. For other CI where editing each pipeline is hard, set PNPM_CONFIG_NPMRC_AUTH_FILE=.npmrc (or NPM_CONFIG_USERCONFIG=.npmrc) in the CI environment to declare the project .npmrc trusted.

See https://pnpm.io/npmrc for full migration details.

Patch Changes

• Stopped expanding environment variables in repository-controlled registry/proxy request destinations and registry credential values from .npmrc, and in workspace registry URLs from pnpm-workspace.yaml. Move dynamic registry URL and token configuration to trusted user, global, CLI, or environment config.

• Resolve package-manager bootstrap dependencies with trusted user or CLI registry and network config, and reject package-manager env-lockfile records that do not use registry package paths with integrity-only resolutions before auto-switch execution.

• Avoid writing packageManagerDependencies to pnpm-lock.yaml when package manager policy is set to onFail: ignore or pmOnFail: ignore #​12228.

• Avoid running dependency-status auto-install when the dependency status is unavailable without a project manifest.

• Using the $ version reference syntax in overrides (e.g. "react": "$react") now prints a deprecation warning. The syntax still works, but catalogs are the recommended way to keep an overridden version in sync with the rest of the workspace. Reference a catalog entry with the catalog: protocol instead.

• Fixed pnpm config get globalconfig to return the global config.yaml path again pnpm/pnpm#11962.

• Fixed bare --color so it does not consume the following CLI flag, allowing command shorthands like --parallel to expand correctly and forms like pnpm --color with current <command> to dispatch the inner command instead of failing with MISSING_WITH_CURRENT_CMD.

• Fix pnpm install ignoring enableGlobalVirtualStore toggle by including it in the workspace state settings check #​12142.

• Security: pnpm now verifies the npm registry signature of a package-manager binary before spawning it, so a cloned repository cannot make pnpm download and execute an arbitrary native binary.

  This covers two paths that select an executable from repository-controlled input:

  • pacquet install engine — declaring pacquet (or @pnpm/pacquet) in configDependencies opts in to pnpm's Rust install engine. pnpm now verifies that the installed pacquet shim and the host's @pacquet/<platform>-<arch> binary carry a valid npm registry signature for their exact name@version, and refuses to run pacquet (failing the command) if the signature does not verify or cannot be checked. The only graceful fallback to pnpm's own engine is when pacquet has no binary for the current platform.
  • automatic version switch / self-update — the packageManager / devEngines.packageManager field makes pnpm download and run a specific pnpm version. pnpm now verifies the registry signature of pnpm, @pnpm/exe, and the host platform binary before installing/spawning them, and refuses to run an engine whose signature does not match a published, signed release. The check runs only on an actual download (store cache miss), so it does not add a network round trip to every command.

  In both cases the signature is verified over the installed integrity, against npm's public signing keys that ship embedded in the pnpm CLI (like corepack), so bytes substituted via a tampered lockfile or a repository-controlled registry fail verification — and a registry the user did not vouch for cannot supply its own signing keys. The signed packument is fetched from the configured registry, so an npm mirror works transparently. Verification fails closed: if it cannot be completed (for example, the registry is unreachable), the command fails rather than running an unverified binary. The embedded keys are kept current by a release-time check against npm's signing-keys endpoint.

• Made peer-dependent deduplication deterministic. When a peer-suffixed package variant was a subset of two or more mutually incompatible larger variants, the variant it collapsed into depended on the order importers were resolved in, which varies between machines. This could resolve the same workspace to different lockfiles on different platforms and make pnpm dedupe --check alternate between passing and failing.

• Reject invalid package names and versions from staged tarball manifests before deriving filenames for pnpm stage download.

• Clarified in CLI help that the pnpm store is trusted shared state and store integrity checks are corruption detection, not a tamper boundary for untrusted store writers.

• Reject reserved manifest bin names ("", ".", "..", and scoped forms such as @scope/..) when resolving a package's bins. These names previously passed the bin-name guard and, when joined to the global bin directory during global remove/update/add operations, could resolve to the global bin directory itself or its parent and have it recursively deleted.

• Require trusted package identity before package-name allowBuilds entries can approve lifecycle scripts for git, git-hosted tarball, direct tarball, and local directory artifacts. To approve one of those artifacts explicitly, use its peer-suffix-free lockfile depPath as the allowBuilds key. Lockfile verification now rejects lockfiles where a registry-style dependency path (name@semver) is backed by a git, directory, or git-hosted tarball resolution (ERR_PNPM_RESOLUTION_SHAPE_MISMATCH), so the dependency path is a reliable artifact identity by the time scripts can run.

• Security: pnpm now verifies the OpenPGP signature of a downloaded Node.js runtime's SHASUMS256.txt before trusting its integrity hashes.

  When a repository requests a Node.js runtime (e.g. via devEngines.runtime / useNodeVersion), the download mirror is repository-configurable through node-mirror:<channel>. The integrity of the downloaded binary was only checked against SHASUMS256.txt fetched from that same mirror — a circular check that a malicious mirror could satisfy by serving a tampered binary together with a matching SHASUMS256.txt. pnpm then executes the binary (for example to run lifecycle scripts).

  pnpm now fetches SHASUMS256.txt.sig and verifies the detached OpenPGP signature against the Node.js release team's public keys, which ship embedded in the pnpm CLI. A mirror that serves a tampered binary cannot also produce a valid signature, so the download fails to verify. The embedded keys are kept current by a release-time check against the canonical nodejs/release-keys list.

  The musl variants from the hardcoded unofficial-builds.nodejs.org mirror are not repository-configurable and are signed by a different key, so they continue to be trusted over TLS.

Patch Changes

• Peer dependency resolution now reuses the peer contexts already recorded in the lockfile when those providers are still present in the dependency graph and still satisfy the peer ranges. This avoids unnecessary peer-context rewrites during lockfile regeneration. Current manifest choices remain authoritative: a newly added, explicitly updated, or aliased direct provider, a changed nested provider, or a locked version that no longer satisfies the range still takes precedence.

• The lockfile verifier now checks that a registry entry pinning an explicit tarball URL points at the artifact the registry's own metadata lists for that name@version. Previously a tampered lockfile could pair a trusted name@version with an attacker-chosen tarball URL (and a matching integrity for those bytes), so the install fetched the attacker's bytes. A mismatch — or any entry that can't be confirmed against the registry — is rejected with ERR_PNPM_TARBALL_URL_MISMATCH. Non-registry resolutions (file:, git-hosted, etc.) and registry entries without an explicit tarball URL (the URL is reconstructed from name+version+registry, so it is inherently bound) are unaffected; non-standard registry tarball URLs (npm Enterprise, GitHub Packages) still pass because they match the metadata.

• Fix pnpm update --recursive --lockfile-only <pkg>@&#8203;<version> crashing with Invalid Version when the catalog entry for <pkg> is a version range (e.g. ^21.2.10) and catalogMode is strict or prefer. The catalog–version comparison now skips the equality check when either side is a range rather than passing a range to semver.eq(), so range specifiers fall through to the existing mismatch handling instead of throwing #​11570.

• Avoided a Node.js crash when pnpm exits after network requests on Windows.

• Fixed packages being materialized into the virtual store without their root-level files (package.json, LICENSE, README, root entrypoints) when multiple pnpm install processes ran against the same store/workspace concurrently. The fast import path used to destructively empty the shared target directory, so a concurrent importer could wipe files another importer had already written; if the surviving files included the package.json completion marker, every later install treated the broken directory as complete and never repaired it. The fast path now imports directly only when it can create the target directory exclusively, and otherwise builds the package in a private temp directory and atomically renames it into place #​12197.

• Fix dependency build scripts not running under the global virtual store (enableGlobalVirtualStore).

  In a workspace install, dependency build scripts are deferred to a single rebuild pass (buildProjects). That pass resolved each package's location from the classic node_modules/.pnpm/<depPathToFilename> layout, which does not exist under the global virtual store — so native dependencies (e.g. packages using node-gyp / prebuild-install) were never built and failed to load at runtime (Cannot find module .../build/Release/*.node).

  buildProjects now resolves the global-virtual-store projection directory (<storeDir>/links/<hash>, computed with the same graph hash the installer uses) when enableGlobalVirtualStore is set, and serializes concurrent builds of the same shared projection so parallel workspace projects don't race on the same directory.

• Don't promote a runtime: dependency (such as the Node.js version from devEngines.runtime or pnpm runtime set) into a catalog when catalogMode is strict or prefer. A runtime: dependency round-trips to devEngines.runtime, which only recognizes the runtime: protocol; cataloging it rewrote the manifest entry to catalog:, which broke that round-trip, stranded it in devDependencies, and left devEngines.runtime untouched.

• Skip lockfile minimumReleaseAge/trustPolicy verification for non-registry tarball protocols (for example file:), so local tarball dependencies are not incorrectly checked against npm registry metadata.

Patch Changes

• Improve pnpm audit performance by pruning non-vulnerable lockfile subtrees and stopping path enumeration once vulnerable findings reach the path cap.
• Avoid crashing when the workspace state cache is partially written or malformed.
• Set npm_config_user_agent for root lifecycle scripts during headless installs.
• Preserve the integrity field of a remote (non-registry) tarball dependency when its lockfile entry is rebuilt. Re-resolving such a dependency without re-fetching it (for example via pnpm update, or when another dependency changes) produced a resolution with no integrity — URL/tarball resolvers only learn the integrity after the tarball is downloaded — so the previously recorded integrity was dropped, making later installs fail with ERR_PNPM_MISSING_TARBALL_INTEGRITY #​12067.
• Normalize a string repository field into the { type, url } object form when creating the publish manifest, matching npm's behavior. Some registries (e.g. Gitea/Codeberg) reject a string repository with a 500 Internal Server Error during pnpm publish #​12099.
• Preserve compatible optional peer versions already present in the lockfile when resolving dependencies.
• Fixed inconsistent resolution of a peer dependency that is shared through a diamond. When a package peer-depends on both another package and one of that package's own peer dependencies (for example @typescript-eslint/eslint-plugin peer-depends on both @typescript-eslint/parser and typescript, and @typescript-eslint/parser peer-depends on typescript), pnpm no longer reuses a hoisted instance of the shared peer that was resolved against a different version #​12079.
