{"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":"2026-09-26T11:46:14.860804188Z","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":"0"},{"fixed":"7e4c8a5d0d2dbe5bf8fd272ff6acafb27d24744f"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"v0.8.0-rc2"}]}},{"type":"GIT","repo":"https://github.com/LibreChat-AI/LibreChat","events":[{"introduced":"bef5c26bed4e5053bdf1936d6ded2c77035c6ee5"},{"last_affected":"bef5c26bed4e5053bdf1936d6ded2c77035c6ee5"}],"database_specific":{"cpe":"cpe:2.3:a:librechat:librechat:0.7.9:-:*:*:*:*:*:*","extracted_events":[{"introduced":"0.7.9-NA"},{"last_affected":"0.7.9-NA"}],"source":"CPE_STRING"}}],"versions":["0.7.9-NA","v0.8.0-rc1","v0.7.9","librechat-1.8.9","v0.7.9-rc1","v0.7.8","v0.7.8-rc1","v0.7.7","v0.7.7-rc1","v0.7.6","v0.7.6-rc1","v0.7.5","v0.7.5-rc2","v0.7.5-rc1","v0.7.4","v0.7.4-rc1","v0.7.3","v0.7.3-rc2","v0.7.3-rc","v0.7.2","v0.7.1","v0.7.0","v0.6.10","v0.6.9","v0.6.6","v0.6.5","v0.6.1","v0.6.0","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.3","v0.3.0","v0.2.0","v0.1.1","v0.1.0","v0.0.6","v0.0.3","v0.0.2","v0.0.1"],"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"}]}
