Conversation
Addresses two Dependabot security alerts in transitive dependencies: - @babel/core (GHSA-4x5r-pxfx-6jf8, low): Arbitrary File Read via sourceMappingURL Comment. Vulnerable versions <=7.29.0. The transitive @babel/core@^7 pulled in via @jest/transform@29.7.0 was resolving to 7.29.0. Bumped to 7.29.7 (first patched 7.x release). - js-yaml (GHSA-h67p-54hq-rp68, moderate): Quadratic-complexity DoS in merge key handling via repeated aliases. Vulnerable versions >=4.0.0 <=4.1.1. The transitive js-yaml@^4.1.0 pulled in via eslint@8.57.1 was resolving to 4.1.1. Bumped to 4.3.0 (first patched 4.x release). Both fixes are lockfile-only (no changes to package.json), performed via 'yarn up --recursive' so no additional 'resolutions' entries are required. Tests, type-check, build, and lint all pass.

Summary
Fixes two Dependabot security alerts affecting transitive dependencies in
yarn.lock. Lockfile-only change — no updates topackage.jsonand no newresolutionsentries required.Vulnerabilities addressed
@babel/core(transitive via@jest/transform@29.7.0)<=7.29.07.29.07.29.7js-yaml(transitive viaeslint@8.57.1)>=4.0.0 <=4.1.14.1.14.3.0After the bump,
yarn npm audit --recursive --all --no-deprecationsreportsNo audit suggestions.Approach
Both advisories are in transitive dependencies where bumping the direct dependent would require a major upgrade (ESLint 8 → 9 with flat-config migration; Jest 29 → 30). Instead, this uses
yarn up @babel/core --recursiveandyarn up js-yaml --recursive, which only rewrites the lockfile entries for the vulnerable ranges to their patched versions:@babel/core@npm:^7.11.6, ^7.12.3, ^7.23.9→7.29.7(still within the ranges requested by babel-jest et al.)js-yaml@npm:^4.1.0→4.3.0(still within the range requested by eslint 8.57.1)js-yaml@npm:^3.13.1is left untouched at3.15.0(unaffected).No new
resolutionsare introduced — the existingresolutionsblock inpackage.jsonis unchanged.Verification
