CVE-2026-45743: Termix has a File-Manager Session Hijack via Missing Ownership Check (IDOR)
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 16 file-manager endpoints in Termix prior to version 2.3.2 do not verify that the requesting user owns the SSH session identified by sessionId. An authenticated attacker who knows or guesses another user's active sessionId can read, write, delete, download, and execute files on the victim's connected SSH host. Version 2.3.2 patches the issue.
