CVE-2026-39940
ChurchCRM has an Open Redirect via the ‘linkBack’ URL Parameter in DonatedItemEditor.php
Summary
ChurchCRM has an Open Redirect via the ‘linkBack’ URL Parameter in DonatedItemEditor.php
Original description
The description as published by the source.
ChurchCRM is an open-source church management system. Prior to 7.0.0, it was possible in many places across the ChurchCRM application to create a link that, when visited by an authenticated user, would redirect them to any URL chosen by an attacker if they clicked 'Cancel' button on the page. For this write-up the DonatedItemEditor.php will be used as an example, however wherever all instances of 'linkBack' should be assessed. This vulnerability is fixed in 7.0.0.
