CyberRota Analysis
AI-GeneratedUnauthenticated attackers can exploit a vulnerability in authentik's SAML implementation, leading to worker process termination and disruption of legitimate traffic. This can result in denial-of-service conditions for users relying on the identity provider. Organizations using authentik prior to versions 2026.2.7, 2026.5.7, and 2026.8.2 should prioritize updating to mitigate this high-severity risk.

Original NVD Description
authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an unauthenticated attacker can submit a malformed SAML message to an authentik deployment using SAML in either the identity-provider or SAML source role. The message can stop the worker handling /application/saml/* or /source/saml/*, causing the requests assigned to that worker to fail. Worker process termination and automatic restart do not destroy database-backed sessions, but continued malicious messages can cause a sustained share of legitimate traffic to fail. Other protocol implementations are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.
