Description

ChurchCRM is an open-source church management system. Versions prior to 6.7.2 have a Stored Cross-Site Scripting (XSS) vulnerability occurs in Create Events in Church Calendar. Users with low privileges can create XSS payloads in the Description field. This payload is stored in the database, and when other users view that event (including the admin), the payload is triggered, leading to account takeover. Version 6.7.2 fixes the vulnerability.
