NVD Description
Note: Versions mentioned in the description apply only to the upstream grafana12.4 package and not the grafana12.4 package as distributed by RHEL.
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. Attackers can request URLs previously fetched by other clients to receive cached responses intended for different users, disclosing sensitive information across clients.
