CVE-2025-50233 is a medium-severity flaw (CVSS 6.5) affecting qcms. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability in QCMS version 6.0.5 allows authenticated users to read arbitrary files from the server due to insufficient validation of the "Name" parameter in the backend template editor. By manipulating the parameter, attackers can perform directory traversal and access sensitive files outside the intended template directory, potentially exposing system configuration, PHP source code, or other sensitive information.
