Technical details
The vulnerability is an authorization bypass (CWE-863) in the mpwem_quick_edit_event AJAX action. The plugin fails to verify that the user owns or has permission to modify the specific post being edited; instead, it only checks a global capability (edit_posts), which is granted to Contributor and higher roles. An authenticated Contributor can craft a direct AJAX request to /wp-admin/admin-ajax.php with an arbitrary post ID and desired post_title and post_status values to modify any post or page. No CSRF protection or nonce verification on the target post is performed. The fix is available in version 5.3.7 and later.
