MEDIUM 6.1EPSS 0.21%

Does this matter?

Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Description

A stored XSS vulnerability in RSMail! component 1.19.20 - 1.22.26 for Joomla was discovered. The issue occurs within the dashboard component, where user-supplied input is not properly sanitized before being stored and rendered. An attacker can inject malicious JavaScript code into text fields or other input points, which is subsequently executed in the browser of any user who clicks on the crafted text in the dashboard.
