Technical details
The allowEdit() method in ApiController.php contains a hardcoded return true statement that bypasses Joomla's component-level and asset-level ACL permission checks. An authenticated backend user with basic access can exploit this to edit any EasyStore record. The vulnerability was resolved by replacing the hardcoded boolean with proper ACL authorization checks via AccessControl::create()->canEdit().
