Ignore two unfixable audit advisories

Adds two GHSAs to auditConfig.ignoreGhsas in pnpm-workspace.yaml. Neither advisory has a patched release yet.

Advisory Package Why it can't be triggered here
GHSA-ch52-4w7c-c8xp http-cache-semantics ≤ 4.2.0 Only exploitable in a shared HTTP cache. Our one path to it is the docs site's update check (@docusaurus/core → update-notifier → got), which isn't a shared cache.
GHSA-vfj7-8cjw-p6xm braces ≤ 3.0.3 Needs attacker-supplied brace patterns. We only reach it through build/test tools (webpack, tailwind, jest, docusaurus), which expand globs from repo config. It isn't in the viewer bundle.

pnpm audit --audit-level high now passes (6 ignored). We should remove these entries once fixed versions come out and clear minimumReleaseAge.

Summary by CodeRabbit

  • Chores
    • Updated dependency audit settings for two findings in supporting documentation, build, and test tools. These changes affect how dependency audit results are reported; they do not change app features or behavior. No changes to the end-user experience are included in this update.

…n pnpm audit

Neither advisory has a published fix. http-cache-semantics and braces are
reached only through docs and build tooling, never with untrusted input.

📝 Walkthrough

Walkthrough

The workspace configuration adds two GHSA IDs to auditConfig.ignoreGhsas, with comments identifying the affected dependencies and their usage.

Changes

Dependency audit exclusions

Layer / File(s) Summary
Add dependency audit exclusions
pnpm-workspace.yaml
Adds ignore entries for GHSA-ch52-4w7c-c8xp and GHSA-vfj7-8cjw-p6xm. Comments describe the affected dependency paths and state that the relevant cache and glob expansion do not use user-supplied input.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Other

Merge Risk: 🔵 Low · up to 7d28f

Approved fork PRs can run contributor-controlled brace patterns in the self-hosted e2e workflow. Defer changes to the Tailwind configs before relying on this audit exclusion.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7d28f

The change reduces dependency-audit coverage, including for a build dependency reached through contributor-editable configuration. Existing execution paths and approval controls remain unchanged, and no new production exposure is established. The supported concern is limited to weakened audit detection and build availability.

Retained concerns

  • Low · security · observed: The new workspace-wide braces exception removes advisory coverage for a build-time dependency reached through PR-editable configuration. Repository-defined globs are not inherently trusted. This weakens audit detection for an existing input route; it does not introduce that route or expand runner authority.
Security review details

Security Blast Radius

  • inferred — The supported denial-of-service scope is build/test process availability, including the existing approved self-hosted Playwright route. The PR changes audit visibility rather than execution authority. CircleCI configuration references an NPM token, but external fork and secret policies are unavailable, so credential exposure or broader independently attackable scope is not established.

Security Findings and Attack Paths

  • inferred — The retained denial-of-service finding concerns PR-influenced Tailwind patterns reaching brace expansion through existing build tooling. Earlier static tracing identifies Tailwind, fast-glob, micromatch, and braces 3.0.3 in that route. The execution path predates this PR; advisory suppression is the introduced control change. The retained assessment records unknown reachability and likelihood and low impact, so a successful runtime exploit is not asserted.

Trust Boundaries and Controls

  • observed — The GitHub gate defers fork PRs modifying pnpm-workspace.yaml before self-hosted execution, while same-repository branches proceed based on repository write authority. The workflow documents contributor approval for ordinary fork runs, and CODEOWNERS assigns workspace-policy reviewers. These are unchanged countercontrols, not proof of equivalent CircleCI isolation or independently verified external enforcement.

Resilience and Maintainability Implications

  • observed — When the CircleCI audit runs and fails, the diagnostic audit command does not erase the failure: the step explicitly exits with failure before installation and package builds. The PR retains this containment behavior for non-ignored advisories.

Hardening Proposals

  • proposed — Treat these entries as explicit risk acceptance: assign an owner and reassessment trigger, distinguish repository-defined patterns from trusted patterns, and remove the exceptions when fixed versions are adopted. This would reduce long-lived control drift without implying that this PR introduced the existing build-input route.

Denial of Service

Reachability: External
Exploitability: Moderate
CWE: CWE-674

Do not treat braces as unreachable from pull-request input. The Playwright workflow checks out PR content and runs the e2e suite, which starts the app’s Rspack server. That server’s CSS rule loads Tailwind with platform/app/tailwind.config.js, whose content patterns use brace expansion; the config also loads Tailwind presets with their own patterns. The fork gate does not defer PRs that change these configs, although fork runs require maintainer approval. Add the app and preset Tailwind configs to the gate’s deferred-path list, or remove this advisory ignore until PR-controlled patterns cannot reach the vulnerable parser.
