Vulnerability Description
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the Pledge Editor renders donation comment values directly into HTML input value attributes without escaping via htmlspecialchars(). An authenticated user with Finance permissions can inject HTML attribute-breaking characters and event handlers into the comment field, which are stored in the database and execute in the browser of any user who subsequently opens the pledge record for editing, resulting in stored XSS. This issue has been fixed in version 7.2.0.
