{"id":"CVE-2025-8850","summary":"Insecure API Design in danny-avila/librechat","details":"In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow. The system allows users to disable 2FA without requiring a valid OTP or backup code, bypassing the intended verification process. This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint '/api/auth/2fa/disable' is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise.","modified":"2026-08-12T03:51:42.555106729Z","published":"2025-10-30T19:59:36.327Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-440"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8850.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/8e615709-f4de-41e2-b194-f0d91ed7c75e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8850.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-8850"},{"type":"FIX","url":"https://github.com/danny-avila/librechat/commit/7e4c8a5d0d2dbe5bf8fd272ff6acafb27d24744f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/danny-avila/librechat","events":[{"introduced":"bef5c26bed4e5053bdf1936d6ded2c77035c6ee5"},{"fixed":"7e4c8a5d0d2dbe5bf8fd272ff6acafb27d24744f"}],"database_specific":{"extracted_events":[{"introduced":"0.7.9-NA"},{"last_affected":"0.7.9-NA"}],"source":["CPE_STRING","REFERENCES"],"cpe":"cpe:2.3:a:librechat:librechat:0.7.9:-:*:*:*:*:*:*"}}],"versions":["0.7.9-NA","v0.8.0-rc1","v0.7.9","librechat-1.8.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-8850.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
