 "title": "ECS <= 4.3.12 - Authenticated (Contributor+) Insecure Direct Object Reference to Dynamic Repeater Binding Modification",
 "description": "The ECS – Ele Custom Skin for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference via the Dynamic Repeater Builder's ecs_drb_save_binding and ecs_drb_break_binding AJAX actions in all versions up to, and including, 4.3.12. This is due to missing validation on a user-controlled key: the handlers only check that the user can edit the supplied post ID and do not check that the element_id:control_key entry in the site-wide binding index belongs to that post. This makes it possible for authenticated attackers, with Contributor-level access and above, to overwrite or remove binding index entries that belong to other users' posts, which turns off the runtime data binding on those pages.",
