The sandbox exited with 1.
Said: `postcss-selector-parser` is now locked at 7.1.6 in `package-lock.json`, so the vulnerable 6.1.4 is gone.

You are a coding agent working in the git repository checked out in the current directory, on pull request #12 of this repository. Issue #11: Upgrade postcss-selector-parser to 7.1.6: fixes GHSA-rj75-hqrm-r3gf `postcss-selector-parser` (npm) has known vulnerabilities with a fix in **7.1.6**. Upgrade it to 7.1.6 or later everywhere it is locked, keeping other changes to what the upgrade needs. | Advisory | Severity | Affected | Fixed in | Summary | | --- | --- | --- | --- | --- | | [GHSA-rj75-hqrm-r3gf](https://osv.dev/vulnerability/GHSA-rj75-hqrm-r3gf) | medium | 6.1.4 | 7.1.6 | PostCSS: Quadratic complexity in flat selector parsing allows CPU exhaustion | Locked in: `package-lock.json` (6.1.4). The acceptance checks pass once no lockfile resolves a vulnerable version and the tests still pass. If the fix needs a major upgrade that breaks the build, change the code that depends on it in the same pull request. --- _Opened by g1t's dependency upkeep.

When you learn something the next agent here would need (how to build or test, a convention, a decision and why, a trap), save it with the remember tool: scope project for this codebase, workspace for what holds across the workspace's projects. One short fact each. Never a secret, a key or a token. recall searches what is kept. Context for this work, from the workspace's context hub.

These pull requests are in progress, and any of them may merge before yours: - #10 Upgrade basic-ftp to 6.2.1: fixes GHSA-c475-qrg2-pj4r (for issue #9), by g1t-agent: nothing pushed yet Keep your change to what your task needs. Where you have to change the same files as one of these, keep your edits small and local so both can merge cleanly: do not reformat, reorder or move code you do not need to change, and do not do work that belongs to one of them. You have g1t's own tools (mcp__g1t__…) for this repository. Use them to work with the other agents and people here rather than around them: if you find something that needs doing outside your task, open an issue for it with create_issue, saying what and why and naming the pull request you are working on, instead of widening your change; to tell another pull request's author something, such as a conflict you can see coming, comment on it with add_comment; to ask the agent working on another pull request something, or hand it work that belongs there, use message_agent with kind question or handoff and your own pull request as from_number, and keep working: the answer reaches you at a later step. Answer what other agents send you with answer_message. If the work mentions a ticket or alert from another system, such as a Jira key like TECH-1234 or a Sentry link, get_context fetches it as it is now. get_pull_request shows another pull request's change and the files it shares with others. The repository's GitHub Actions workflows run on every commit you push: list_workflow_runs with your pull request's number shows how they went, and get_workflow_run and get_job_logs show why one failed. Mention anything you opened, asked or answered in your summary. Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer: plain sentences, no headings, no emoji, no checklists, and nothing about whether anything was committed or pushed. Say what you did not verify.- This checkout is not the repository's own branch, so its CLAUDE.md and .claude settings, hooks, MCP servers and commands were not loaded.

git commit -qam "Upgrade postcss-selector-parser to 7.1.6 (GHSA-rj75-hqrm-r3gf) Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>" && git log --oneline | head -1 `postcss-selector-parser` is now locked at 7.1.6 in `package-lock.json`, so the vulnerable 6.1.4 is gone. It only reaches the repo through `postcss-nested` (pulled in by tailwind), and `postcss-nested` ^6 asks for ^6.1.1, so a plain upgrade could not move it. I added an `overrides` entry `"postcss-selector-parser": "^7.1.6"` to `package.json` next to the existing `fflate` override, then refreshed the lockfile. The only changes are that override and the lockfile entry (version, resolved URL, integrity hash). After the change, `npm ci --ignore-scripts` and `npm test --if-present` finished without errors, and `npm run typecheck` exited 0. I did not run the lockfile version-check command from the issue, but the lockfile now shows 7.1.6 for that entry. I did not confirm that the Tailwind/PostCSS build still works at runtime. `postcss-nested` 6.x was written against the 6.x parser, but nothing in the typecheck or tests exercises that. I also did not run `cargo test`, as the change doesn't touch Rust code. An alternative is to upgrade `postcss-nested` to 7.0.2, which depends on the 7.x parser directly. I didn't take it because tailwind pins `^6.0.1`, so it would have needed its own override anyway. <g1t-learned>[{"kind":"gotcha","scope":"project","text":"postcss-selector-parser is only a transitive dep of postcss-nested ^6 (via tailwind), so bumping it needs an npm `overrides` entry in the root package.json.","evidence":"package-lock.json: postcss-nested requires ^6.1.1; no direct dependency; overrides block added in package.json"},{"kind":"gotcha","scope":"project","text":"`npm install --package-lock-only` did not move the locked version after adding an override; `npm update <pkg> --package-lock-only` did.","evidence":"lockfile stayed at 6.1.4 until npm update postcss-selector-parser --package-lock-only"},{"kind":"fact","scope":"project","text":"`npm ci` takes more than 2 minutes here; run it in the background or with a long timeout, and use --ignore-scripts to skip workerd's install script.","evidence":"foreground npm ci exceeded the 120s tool timeout"}]</g1t-learned>
