fix(deps): bump @babel/core to ^7.29.6 to resolve GHSA-4x5r-pxfx-6jf8#839
Merged
Conversation
Adds a pnpm override forcing @babel/core to a patched version, resolving the arbitrary file read via sourceMappingURL comment vulnerability (CVE-2026-49356, low severity) pulled in transitively via @sentry/esbuild-plugin -> @sentry/bundler-plugin-core. Closes Dependabot alert #184.

## Summary Resolves 3 Dependabot alerts (**#186, #187, #188**), all the same advisory across both projects. - **Advisory:** [GHSA-h67p-54hq-rp68](GHSA-h67p-54hq-rp68) / CVE-2026-53550 — *js-yaml: Quadratic-complexity DoS in merge key handling via repeated aliases* (medium severity) - **Vulnerable:** \`>= 4.0.0, <= 4.1.1\` → **patched:** \`4.2.0\` These alerts were opened by the post-merge rescan right after #839 landed (newly-published advisory), not caused by that change. ## Fix | Alert | Manifest | Relationship | Change | |---|---|---|---| | #187 | root \`package.json\` | direct devDep | bump pinned \`js-yaml\` \`4.1.1\` → \`4.2.0\` | | #188 | root \`pnpm-lock.yaml\` | direct devDep | regenerated → \`4.2.0\` | | #186 | \`docs/pnpm-lock.yaml\` | transitive (astro/starlight) | \`pnpm.overrides\` \`js-yaml: ^4.2.0\` → resolves to \`4.3.0\` | - Root uses an exact pin (matching the repo's pinned-devDep convention, e.g. \`tar\`); docs uses an override (matching the docs override style) since js-yaml is transitive there. - Both lockfile diffs are 100% js-yaml-scoped — no unrelated drift. No \`@babel/core\`/other packages touched. ## Verification - Root: \`pnpm build\` ✅, \`pnpm test\` ✅ (1025 passed, 1 skipped), \`pnpm lint\` ✅ (0 errors), \`pnpm format:check\` ✅ (tracked files) - Docs: \`pnpm build\` ✅ (27 pages built) - \`grep "js-yaml@" pnpm-lock.yaml docs/pnpm-lock.yaml\` — only \`4.2.0\`/\`4.3.0\` remain; \`4.1.1\` gone. (\`@types/js-yaml\` is type-defs only, not the vulnerable package.)

Summary
Resolves the only open Dependabot alert on the repo (#184).
Dependency chain:
```
@sentry/esbuild-plugin@2.23.1 (direct devDep)
└─ @sentry/bundler-plugin-core@2.23.1
└─ @babel/core (vulnerable)
```
Fix
Added a `pnpm.overrides` entry `"@babel/core": "^7.29.6"`, following the repo's established pattern for transitive-dependency vulnerabilities. `pnpm install` bumped the whole `@babel/*` toolchain to `7.29.7` in lockstep.
Compatibility: the consumer `@sentry/bundler-plugin-core@2.23.1` declares `@babel/core: ^7.18.5` (and the internal `@babel/helper-module-transforms` peer range is `^7.0.0`); `7.29.7` satisfies both, and `^7.29.6` stays within the 7.x major so it cannot regress into the vulnerable range or the separate `8.0.0-alpha … <8.0.0-rc.5` vulnerable range. A bare `@babel/core` override key is correct here since there is a single copy in the lockfile. Upgrading `@sentry/esbuild-plugin` itself was rejected as it would require a 3-major jump (2.x → 5.x).
