Name of the Vulnerable Software and Affected Versions
EspoCRM versions prior to 9.3.5
Description
A business logic flaw involving broken access control allows low-privileged users to pin arbitrary notes without the necessary edit permissions for the parent object. This occurs due to a write-first, authorize-later execution flaw in the backend API where the server modifies the pinned status in the database before completing authorization, despite returning a 403 Forbidden error. The issue is located in the server-side processing of the 'POST /api/v1/Note/{id}/pin' endpoint, specifically within the
process() method in application/Espo/Tools/Stream/Api/PostNotePin.php, which calls getNote($id) before checkParent($note).Recommendations
Update to version 9.3.5.
