Dependabot security bump — postcss-selector-parser 6.1.1 → 6.1.4

This is a clean, low-risk devDependency patch that should be merged promptly.

What changed

Version Change
6.1.2 Fixed erroneous trailing combinators in pseudo-selectors
6.1.3 Backport of CVE-2026-9358 (GHSA-w9m9-85wc-3x92 / SNYK-JS-POSTCSSSELECTORPARSER-16873882)
6.1.4 Tolerate non-node children when serializing selectors (serialization robustness)

Security note

CVE-2026-9358 is the primary driver. postcss-selector-parser is a devDependency here (build/lint tooling only — Stylelint, PostCSS transforms), so the vulnerability surface is confined to the build process and does not affect consumers of the published @phillips/seldon npm package at runtime. That said, patching promptly is still the right call.

Diff assessment

The only change in package-lock.json is:

  • version: 6.1.16.1.4
  • resolved/integrity: updated to match the new tarball
  • "license": "MIT" field added (cosmetic — npm lockfile v3 now records license inline)

No new transitive dependencies were added. The existing cssesc ^3.0.0 and util-deprecate ^1.0.2 peer requirements are unchanged.

I would approve this. Merge as soon as CI is green.

🟢 Dependency Upgrade Risk: Low

What is postcss-selector-parser?

postcss-selector-parser is a library that parses CSS selector strings into an AST, used internally by PostCSS plugins to analyze and transform selectors. It is not a direct dependency of seldon — it appears only in the lockfile as a transitive dependency of stylelint and stylelint-scss (both direct dev-dependencies). No application source code, component, or PostCSS config in the seldon repo imports it directly.

In practice it is a linting tooling detail: it runs only during npm run lint and has zero presence in the published seldon package or in any runtime execution path.

What changed (6.1.1 → 6.1.4)?

  • 6.1.2: Fixed erroneous trailing combinators in pseudo-selectors (a linting correctness fix).
  • 6.1.3: Fixed CVE-2026-9358 (GHSA-w9m9-85wc-3x92) — a vulnerability backported to the 6.x line. Since this library only runs during linting (not production), the actual attack surface is nil.
  • 6.1.4: Tolerate non-node children when serializing selectors (defensive parser fix).

No breaking changes, no API surface changes.

Why Low?

This is an indirect dev-only transitive dependency used exclusively by the linting pipeline. It has no presence in the production build or the published @phillips/seldon package. All three patch changes are additive fixes. The only possible regression would be a change in how stylelint or stylelint-scss interprets certain selectors — and even then it would only affect the lint output, not the application.

Regression Test Checklist

  • Lint passes: Run npm run lint and confirm it completes with no new errors or warnings compared to before.
  • Build passes: Run npm run build to confirm the package still compiles correctly.
  • Unit tests pass: Run npm run test to confirm component tests are green.
