…5p4m-2wfm-xmqj] Quadratic CPU consumption in !!omap resolution, affecting both the 3.x and 4.x lines. #27 bumped to 4.3.0 the day before 4.3.1 shipped, so this picks up the tail of that plus the nested 3.x copy under @istanbuljs/load-nyc-config. Both are devDependencies (eslint and jest), so nothing reaches consumers of the published package. Lockfile-only, within the existing ranges. npm audit goes from 1 high to 0.

Fixes dependabot alert #82 (GHSA-52cp-r559-cp3m / CVE-2026-59869) — js-yaml < 4.3.0 can burn quadratic CPU on chained YAML merge keys. Transitive dev dependency via eslint; lockfile-only change, no package.json bump needed.
