What is CVE-2026-45746?

The Termix Web Management Platform includes a vulnerability related to Broken Access Control, specifically in its File Manager feature. This issue stems from inadequate validation of the sessionId parameter, allowing attackers to exploit the backend's trust in a client-controlled identifier. As a result, unauthorized users can access active File Manager sessions belonging to others, enabling them to read, write, upload, or execute commands on another user’s remote VPS instance. This flaw poses significant risks, as it directly exposes users to potentially harmful interactions with each other's filesystems. Version 2.3.2 addresses this vulnerability with necessary security enhancements.
