{"id":"CVE-2026-55181","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-55181","generatedAt":"2026-10-28T03:30:49.090Z","title":"This bypasses the intended OIDC disable switch.","description":"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.","published":"2026-09-30T17:16:47.000Z","lastModified":"2026-09-30T20:17:34.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.4,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L"},"cwe":["CWE-284"],"affected":[],"epss":{"score":0.00598,"percentile":0.48341,"date":"2026-10-26","history":[{"date":"2026-10-01","score":0.00682,"percentile":0.50693}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%).
