CVE-2026-94613: Goauthentik Authentik

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Goauthentik Authentik: before 2026.2.7 (fixed in 2026.2.7); from 2026.5.0, before 2026.5.7 (fixed in 2026.5.7); from 2026.8.0, before 2026.8.2 (fixed in 2026.8.2)
