http-cache-semantics through 4.2.0 Cross-Client Cache Disclosure via Vary Wildcard
http-cache-semantics through 4.2.0 contains a cache validation vulnerability in the _varyMatches() function that fails to properly validate Vary header wildcards due to byte-for-byte string comparison.

CVE-2026-93748 High · 7.5 CWE-524 Sep 18, 2026
http-cache-semantics through 4.2.0 Cross-User Cache Disclosure via max-stale
http-cache-semantics through 4.2.0 fails to properly validate security-zeroed cache entries when processing client max-stale directives, allowing unauthenticated attackers to retrieve cached responses belonging to other users.
