A vulnerability exists in the X.509 client certificate authenticator of Keycloak. When CRL Distribution Point checking is enabled, the server improperly validates file paths in client certificates. This flaw allows an attacker to supply a crafted certificate that can cause the server to read sensitive local files or exhaust memory by loading very large files, potentially leading to information disclosure or a system crash.
