What is CVE-2026-45749?

CVE-2026-45749 is a high-severity authentication bypass vulnerability in Termix-SSH Termix, published on 5 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. The `POST /users/totp/disable` and `POST /users/totp/backup-codes` endpoints in Termix prior to version 2.3.2 accept the account password as a sole authentication factor for MFA-critical operations. An attacker who obtains a user's password (phishing, credential stuffing, the passwordHash leak in GHSA-xxxx) can disable TOTP entirely or regenerate backup codes, without ever possessing the TOTP device or knowing a valid TOTP code. This renders two-factor authentication ineffective. Version 2.3.2 patches the issue.

Weakness: CWE-308
