{"id":"CVE-2025-8850","state":"PUBLISHED","title":"Insecure API Design in danny-avila/librechat","description":"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.","publishedAt":"2025-10-30T19:59:36.327Z","updatedAt":"2025-11-05T14:57:26.783Z","severity":{"score":3.1,"label":"Low","version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"@huntr_ai"},"assigner":"@huntr_ai","products":["danny-avila danny-avila/librechat"],"affected":[{"vendor":"danny-avila","product":"danny-avila/librechat","versions":[{"version":"unspecified","status":"affected","lessThan":"v0.8.0-rc2","versionType":"custom"}]}],"references":["https://huntr.com/bounties/8e615709-f4de-41e2-b194-f0d91ed7c75e","https://github.com/danny-avila/librechat/commit/7e4c8a5d0d2dbe5bf8fd272ff6acafb27d24744f"],"weaknesses":["CWE-440"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/8xxx/CVE-2025-8850.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-8850","state":"PUBLISHED","datePublished":"2025-10-30T19:59:36.327Z","dateUpdated":"2025-11-05T14:57:26.783Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2025-08-10T19:01:03.291Z"},"containers":{"cna":{"title":"Insecure API Design in danny-avila/librechat","descriptions":[{"lang":"en","value":"In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow.
