CVE ID :CVE-2026-105301
Published : Oct. 5, 2026, 6:16 a.m. | 1 hour, 14 minutes ago
Description :A flaw was found in the X.509 client-certificate authenticator of Keycloak, a solution for identity and access management. The issue occurs when the server is configured to check certificate revocation using CRL Distribution Points or OCSP. An attacker can provide a specially crafted certificate that points to a malicious server, causing Keycloak to make unauthorized outbound requests to internal or external endpoints before the certificate is fully validated. This can lead to a blind server-side request forgery (SSRF) attack.
Severity: 4.0 | MEDIUM
