{"schema":"threatline.record/2","record":{"id":"CVE-2026-55181","aliases":["GHSA-rg7c-vpfp-2w43"],"summary":"Tugtainer: OIDC login remains accessible when OIDC_ENABLED is false","details":"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.","categories":["Unclassified"],"product":"tugtainer","vendor":"Quenary","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55181","source_modified_at":"2026-09-30T19:50:41.889Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"tugtainer","vendor":"Quenary","versions":[{"version":"< 1.30.3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":9.4,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00598,"percentile":0.47971,"score_date":"2026-10-23"},"published_at":"2026-09-30T16:57:15.306Z","modified_at":"2026-09-30T19:50:41.889Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55181","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T19:50:41.889Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55181","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Quenary/tugtainer/security/advisories/GHSA-rg7c-vpfp-2w43","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/Quenary/tugtainer/commit/76371db679334b002d4af544b0f3b8587ad86f52","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Quenary/tugtainer/releases/tag/v1.30.3","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"total","assessed_at":"2026-09-30T19:50:35.786345Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T19:50:41.889Z","content_hash":"44fc03969fd58f10d6941d5c3755d1aad09d51dfdd49ad754755740a544dc5aa"}}
