## What is CVE-2025-8850?

CVE-2025-8850 is a low-severity vulnerability in Librechat Librechat, published on 30 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-440 (Expected Behavior Violation)
