fix: upgrade js-yaml to 3.15.2 to resolve GHSA-2883-xcg3-v3hh - #1111
Merged
Conversation
A new advisory published 2026-09-08 flags js-yaml below 3.15.2 for unbounded CPU use when maxTotalMergeKeys sees empty merge sources. The finding is dev-only and transitive, reached through jest via @istanbuljs/load-nyc-config@1.1.0, which already permits 3.15.2 inside its existing range. Applied with cve-lite --fix as a within-range refresh, so package.json is unchanged and no baseline entry is needed.

main.GHSA-2883-xcg3-v3hhflags js-yaml below 3.15.2 for unbounded CPU use whenmaxTotalMergeKeysencounters empty merge sources. We resolve3.15.1, so thescan reported one new finding above baseline and the ratchet gate exited 1.
The finding is dev-only and transitive, reached through
jestvia@istanbuljs/load-nyc-config@1.1.0, which already allows3.15.2in itsexisting range. Applied with
cve-lite . --fix, which took it as a within-rangerefresh, so
package.jsonis untouched and no override or baseline entry wasneeded.
Rescan afterwards reports no known vulnerabilities. Full suite is green at 1790
tests and the build is clean.
Closes #1110
