From 8ab543d9490de1d84b8ec2178bbd356544e864d0 Mon Sep 17 00:00:00 2001 From: Petr Plenkov Date: Tue, 21 Apr 2026 10:33:55 +0200 Subject: [PATCH 1/4] security: anchor github.com host match in detectGithubRepo The previous `url.includes('github.com')` check matched github.com anywhere in the remote URL, including in paths or subdomains such as https://evil.example/github.com/x/y or https://github.com.attacker.com/x/y. Replace the substring check with a regex that anchors github.com to the actual host component for https(s)://, git://, git+ssh://, ssh://, and SCP-style remotes.

The combined regex in the previous commit had cyclomatic complexity 31 (> 20 allowed by SonarCloud `typescript:S5843`). Behaviour and the `js/incomplete-url-substring-sanitization` fix are preserved — host match is now anchored via `URL.hostname` or an explicit SCP host capture, so substrings like `github.com.attacker.com` still cannot match.

The port was captured as part of the path and then rejected by parseOwnerRepo, silently disabling trusted-publisher auto-detection. The SCP branch is now skipped whenever the input contains `://`, so URL-form remotes fall through to `new URL()`. * CodeRabbit — the previous shape regex `[^/]+/[^/.]+?` rejected valid GitHub repos with dots in the name (e.g. `owner/repo.name`) and accepted shell metacharacters in the owner segment. The value flows unquoted into a shell command at `plugin.ts` line ~126 (`--trust-repo=${trustRepo}`), so a strict allow-list is enforced before return: `^[A-Za-z0-9_.-]+/[A-Za-z0-9_.-]+$`.
