Description

ChurchCRM is an open-source church management system. Prior to 6.5.3, a Stored Cross-Site Scripting (Stored XSS) vulnerability in the admin panel’s group-creation feature allows any user with group-creation privileges to inject malicious JavaScript that executes automatically when an administrator views the page. This enables attackers to steal the administrator’s session cookies, potentially leading to full administrative account takeover. This vulnerability is fixed in 6.5.3.
