Harden security after Codex audit and move hosting to Coolify - #4
Merged
Conversation
Seven rounds of Codex Daybreak (xhigh) security review, each verified and fixed. Highlights: Server - Refuse to start in production without a strong APP_SECRET; data dir 0700 and state file 0600, enforced fail-closed for existing installs. - Login: per-account+address and per-address attempt limits counted at admission, bounded concurrency, dummy scrypt for unknown users, length caps; CLI enforces the same password policy. - Seed probe: fail-closed public-IP check (IPv4 special ranges, IPv6 only 2000::/3 minus specials), no redirects, 400 on blocked targets. - Repository policy: https-only, no credentials, ALLOWED_REPO_HOSTS and ALLOWED_REPOS allowlists, git check-ref-format emulation, full 40-hex commit pins; enforced on save, at publish (atomically, with a 409 on any concurrent change to published inputs), and at the manifest. - Every published release carries both commit pins; empty pins are resolved from the ref via git smart HTTP (strict pkt-line parser, bounded body, exact media type). - Public responses redact repository credentials; no-store on /api and downloads; nosniff/frame/referrer headers; PUBLIC_URL and per-peer trust-proxy handling for generated origins. - Node status history stores counts only and at most one sample/50s. - Pillar configs bind RPC to loopback with no browser origins; seed and base configs stay public for the explorer and faucet. Node bootstrap agent - systemd ExecStartPre gate (znn-testnet-verify-znnd) refuses to start a znnd whose embedded git revision differs from the pinned commit, was built from a modified tree, or when no release has been applied. - Deployment repo and go-zenon are checked out at exactly the pinned commit (fetch by hash, or the ref's history as fallback); go-zenon is built from a local file:// checkout so releases stay installable after the branch moves. - Transient failures retry via cron; only proven integrity failures are sticky (--retry clears them). Atomic pin and artifact writes, errexit kept active inside install_release, cron persists custom paths. Container and deployment - Node 24, npm ci, runs as the node user via an entrypoint that fixes volume ownership before dropping privileges. - Standalone Caddy binds 127.0.0.1 by default; devnet ports too. - Replace the Portainer stack with docker-compose.coolify.yml; README documents Coolify setup, runtime variables, repository policy, and verification. Dependencies: audit fixes plus ws and qs overrides. Tests: 46 tests (npm test) covering policy, refs, limiter, IP guard, snapshot keys, and the generated bash verifier/agent helpers, including a real Go build through the pinned checkout.

Inline comments:
In `@src/server/bootstrap-script.ts`:
- Around line 319-328: Update record_install_failure to merge failedKey,
eventId, lastError, and failedAt into the existing INSTALL_STATE_FILE JSON
document instead of replacing it, preserving install_release state such as
desiredKey, binaryKey, verifiedCommit, installedAt, goZenon, and deployment for
--retry.
In `@src/server/rate-limit.ts`:
- Line 75: Update the rate-limiter admission flow so pruning occurs only when
admitting a key not already present in the buckets map. Ensure existing buckets,
including the oldest blocked key, are checked and preserved before any capacity
eviction; only then evict enough entries to insert a new key while retaining the
existing maxKeys behavior.
In `@src/shared/types.ts`:
- Around line 235-236: Update the node-status history flow around
historySample(), receiveNodeStatus(), and updateState() so appended history
samples omit lastError while the latest status continues to retain it. Avoid
spreading or persisting lastError in each historical sample, preserving the
existing history retention and schema behavior.

- Rate limiter: evict only when inserting a new key and never the key being admitted, so a blocked key keeps its history when the map is full. Regression test added. - Node status history: drop node.lastError from retained samples; it stays on the latest report. - record_install_failure: keep replacing the install state (a --retry must rebuild and re-verify rather than take the fast path), make the intent explicit, and write the file atomically. Test asserts the install identity is cleared. - Bootstrap tests: run git with signing and hooks disabled and a timeout, so a developer's global gpgsign config cannot stall them.

243-248: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick winEnforce ref reachability for explicit commit pins
releasePolicyErrorsvalidates only the SHA format, and publication preserves explicit pins without resolving them from their refs. After the fallback fetch,checkout_pinnedusesgit cat-file -e "$commit^{commit}", which proves only that the commit object exists. It does not prove that the commit is reachable from$ref. An existing, ref-unrelated pin can therefore be checked out and deployed under the named ref. Reject such pins during publication or verify reachability before checkout.🤖 Prompt for AI Agents
