CVE-2026-105301 (GCVE-0-2026-105301)
Vulnerability from cvelistv5

This candidate was rejected after further investigation determined that it is not a security vulnerability. The client certificate chain is validated during mTLS negotiation at the TLS layer or reverse proxy before Keycloak processes CRL Distribution Point or OCSP URLs, so only certificates issued by a CA explicitly trusted by the administrator can trigger these requests.
