Technical details

A reflected cross-site scripting (XSS) vulnerability exists in the Phoca Commander extension for Joomla, versions 5.0.0 through 6.1.1. The issue stems from improper neutralization of user-supplied input during web page generation (CWE-79). An unauthenticated remote attacker can exploit this by tricking a user into clicking a malicious link, leading to the execution of arbitrary JavaScript in the context of the victim's browser session. This could result in unauthorized access to administrative functions or session hijacking. The vulnerability has been assigned a CVSS 4.0 base score of 5.1 by the Joomla! Project.
