## Description

The Hostinger Reach plugin for WordPress is vulnerable to Insecure Direct Object Reference via the Elementor form synchronization in all versions up to, and including, 1.8.9. This is due to the sync that runs when an Elementor post is published updating any existing form record whose ID matches a Reach widget form ID, without checking that the form belongs to the post being published. This makes it possible for authenticated attackers, with Author-level access and above, to reassign Reach form records that belong to other posts to the Elementor integration. As a result, those forms are moved out of their original integration and their owners can no longer update their contact list settings. Elementor must be active.
