Executive brief
ChurchCRM is an open-source management system used by churches to track members, donations, and activities. A security flaw in the software allows an attacker to trick a logged-in administrator into unintentionally deleting important records, such as fundraiser data, notes, or property classifications. This occurs if the administrator visits a malicious website while logged into ChurchCRM, potentially leading to significant data loss and operational disruption.
Technical details
A Cross-Site Request Forgery (CSRF) vulnerability exists in ChurchCRM versions 7.2.2 and earlier due to the use of HTTP GET requests for destructive operations without CSRF token validation. The affected endpoints—FundRaiserDelete.php, PropertyTypeDelete.php, and NoteDelete.php—perform record deletions based solely on GET parameters and role-based authorization. Because the application's session cookies use 'SameSite=Lax' and the endpoints do not validate Origin, Referer, or Fetch-Metadata headers, an attacker can trigger these deletions via a top-level navigation (e.g., a link or window.location assignment) from a malicious site. Successful exploitation allows for the unauthorized deletion of fundraisers, notes, and property types, including cascaded deletions of associated records. The issue is resolved in version 7.3.2.
