Name of the Vulnerable Software and Affected Versions ChurchRota version 2.6.4

Description The issue allows for authenticated remote code execution. It is possible to upload and execute an arbitrary file without needing file upload permission, by sending a POST request to the "resources.php" API endpoint.

Recommendations For ChurchRota version 2.6.4, consider restricting access to the "resources.php" endpoint until a fix is available. As a temporary workaround, limit the ability to upload files to only necessary users to minimize the risk of exploitation.
