Impact
http-cache-semantics 4.2.0 (bundled in npm 12.1.0, the current release) has no fixed version. Vary:* wildcard bypass in _varyMatches(). Tracked upstream at kornelski/http-cache-semantics#57, opened 2026-09-17, still open. Confirmed via NVD (published 2026-09-18) and npm registry (4.2.0 remains npm's latest release).
