{"schema":"threatline.record/2","record":{"id":"CVE-2026-55494","aliases":["GHSA-wgw2-c96g-p7h7"],"summary":"Tugtainer: Unauthenticated access to Tugtainer Agent Docker management APIs when AGENT_SECRET is unset","details":"Tugtainer is a self-hosted app for automating updates of Docker containers. Prior to version 1.30.4, Tugtainer Agent allows unauthenticated access to Docker management APIs when AGENT_SECRET is not configured. The Agent uses request signatures to protect its API routes. However, in agent/auth.py, the signature verification function returns successfully if Config.AGENT_SECRET is empty. This causes protected Agent APIs to become accessible without authentication. This issue has been patched in version 1.30.4.","categories":["Unclassified"],"product":"tugtainer","vendor":"Quenary","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55494","source_modified_at":"2026-09-30T17:13:11.077Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"tugtainer","vendor":"Quenary","versions":[{"version":"< 1.30.4","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.0064,"percentile":0.50023,"score_date":"2026-10-23"},"published_at":"2026-09-30T16:58:27.259Z","modified_at":"2026-09-30T17:13:11.077Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55494","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T17:13:11.077Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55494","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-wgw2-c96g-p7h7","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/Quenary/tugtainer/commit/0052a5544e187a4d12f771838a8a23ca4afb61cd","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Quenary/tugtainer/releases/tag/v1.30.4","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":"2026-09-30T17:12:48.476039Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T17:13:11.077Z","content_hash":"35d6c4cb371148057db9ffdc3838b33d81c9ea32af3ecdbd98de16cd54f4f039"}}
