CVE-2026-45746

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the File Manager functionality in Termix contains a critical Broken Access Control vulnerability due to improper validation of the sessionId parameter. The backend trusts a client-controlled identifier without verifying that it belongs to the authenticated user. This allows an attacker to manipulate the value and access active File Manager sessions belonging to other users. Since these sessions are tied to SSH connections to remote VPS instances, exploitation allows unauthorized interaction with another user's remote filesystem. Because the File Manager exposes functionality such as file reading, writing, uploading, and execution, this vulnerability enables direct command execution on another user's VPS (RCE). Version 2.3.2 patches the issue.
