Attackers can register via the unauthenticated /api/v1/system/user/register endpoint, log in, and forge an HS256 token keeping their session_id but naming the superuser in user_name to gain superuser privileges.","categories":["Unclassified"],"product":"FastapiAdmin","vendor":"fastapiadmin","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111642","source_modified_at":"2026-10-16T19:21:12.720Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FastapiAdmin","vendor":"fastapiadmin","versions":[{"version":"0","lessThanOrEqual":"3.0","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0036,"percentile":0.28581,"score_date":"2026-10-23"},"published_at":"2026-10-16T17:39:12.365Z","modified_at":"2026-10-16T19:21:12.720Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-111642","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T19:21:12.720Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-111642","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@hieuPenguinnn/fastapiadmin-unauthenticated-autologin-and-hardcoded-jwt-secret","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/fastapiadmin/FastapiAdmin/blob/v3.0/backend/app/config/setting.py#L67","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/fastapiadmin/FastapiAdmin/blob/v3.0/backend/app/core/dependencies.py#L72-L112","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/fastapiadmin-through-3.0-hard-coded-jwt-secret-privilege-escalation","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-16T19:20:27.537959Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T19:21:12.720Z","content_hash":"ed625503495d97fcf9581f6fe4a4eb1949c370e45a0e66c0e1ba955cfeee79ac"}}
