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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"abyssal","depthScore":64,"depthScoreParts":{"impact":51.7,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":213959,"id":"CVE-2026-55181","ts":1790799891791,"field":"exploit_available","old":"false","new":"true"}]}
