Conversation
…on packages (SRE-4394) js-yaml < 3.15.0 is a transitive devDependency (via @istanbuljs/load-nyc-config, jest's coverage tooling) in all three npm subdirectories. Dependabot never opened a PR for it since it can't bump a transitive dep directly. Same fix pattern as the SRE-4373 undici fix (#110): pin via `overrides` rather than waiting on the parent package. Verified via npm audit (0 vulnerabilities, was 1 moderate each) and confirmed js-yaml never appears in the built lib/index.js bundles (dev/test only, never shipped in the action runtime).

Summary
Fixes 3 unlinked Dependabot security alerts (#168, #169, #170 — all the same
GHSA-h67p-54hq-rp68 /
CVE-2026-53550, js-yaml < 3.15.0, CVSS 5.3 medium) across
github-release-download,set-environment-variables, andsetup-terraform.js-yaml is a transitive devDependency pulled in by
@istanbuljs/load-nyc-config(jest's coverage tooling) — never a direct dependency, so Dependabot never opened
a PR for it. Same shape and same fix as the SRE-4373 undici fix (#110): add an
overridesentry to force the patched version rather than waiting on the parentpackage to bump its own dependency.
