MFA bypass in Termix TOTP disable and backup code endpoints
CVE-2026-45749 affects Termix, a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. In versions prior to 2.3.2, the POST /users/totp/disable and POST /users/totp/backup-codes endpoints permitted MFA-sensitive account operations using only the account password as authentication. As a result, an attacker who has obtained valid user credentials could disable TOTP protection entirely or regenerate backup codes without possessing the enrolled TOTP device and without supplying a valid TOTP code. This is an authentication design flaw affecting MFA-critical workflows and effectively defeats the intended second factor for those operations.

Impact
What an attacker gets, and what they’ve been doing with it.
Mitigation
If you can’t patch tonight, do this now.
POST /users/totp/disable and POST /users/totp/backup-codes, and alert on unexpected MFA changes. Force password resets for potentially exposed accounts, especially where phishing, credential stuffing, or password-hash exposure is suspected. Review and revoke regenerated backup codes where possible. These measures reduce exposure but do not fully remediate the underlying flaw.Remediation
Patch, then assume compromise.
