CVE-2026-55181

9.4 CRITICAL 0.6% exploit odds Fix listed Auth & access Network gear

What it is

Tugtainer is a self-hosted app for automating updates of Docker containers. Prior to version 1.30.3, Tugtainer's OIDC authentication can still be initiated even when OIDC_ENABLED=false. The /auth/oidc/enabled endpoint correctly reports that OIDC is disabled. However, a direct request to /auth/oidc/login still starts the OIDC login flow, returns HTTP 302, sets an oidc_state cookie, and redirects the user to the configured OIDC authorization endpoint. This bypasses the intended OIDC disable switch. This issue has been patched in version 1.30.3.
