Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🟡 Moderate · up to The dependency update still allows future 3.x versions instead of locking js-yaml to 3.15.2, which reduces reproducibility and does not meet the repository’s dependency-pinning requirement.

Pin the direct js-yaml dependency exactly.
The lockfile resolves patched versions, but the caret range permits future 3.x versions after lockfile regeneration and does not comply with the supply-chain policy. Change the direct dependency to "js-yaml": "3.15.2".

Looks like these versions are all within the semver range so you can just update the yarnlock without adding version overrides

Analysis / Root cause:
CVE-2026-84375: js-yaml versions 3.0.0 to before 3.15.2 and 4.0.0 to before 4.3.2 allow
Denial of Service via YAML documents that use merge keys (
<<) with aliased empty mappings.The
maxTotalMergeKeysrate limiter does not count empty-mapping merge sources, so a craftedpayload can cause unbounded CPU consumption while the limit is never reached.
