# srimax output messenger: Output Messenger before 2.0.63 was vulnerable to a directory traversal attack through improper file path handling

Srimax Output Messenger, an enterprise chat application, has a directory traversal flaw that lets a request reach files outside its intended folder. An attacker can read sensitive files such as configuration data, and CISA reports active exploitation.

_Summary, check and fix written by a model from the sources; labelled as such._
