Technical details
A stored cross-site scripting (XSS) vulnerability exists in the Joomla! CMS 'com_templates' component within the file management view. The issue stems from a lack of proper output escaping of user-supplied data. An attacker with high privileges (PR:H) can exploit this by injecting malicious scripts that execute in the context of another user's browser session when they interact with the file management interface. The vulnerability affects Joomla! versions 4.0.0 through 5.4.6 and 6.0.0 through 6.1.1. It has been addressed in versions 5.4.7 and 6.1.2.
