Vulnerability Title
Builderall for WordPress <= 3.0.2 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Meta Modification via 'ba_cheetah_data[post_id]' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Builderall Cheetah For Wp plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the disable() function in versions up to, and including, 3.0.2. The wp_ajax_ba_cheetah_disable AJAX handler is registered without any capability or nonce verification, and the target post_id is sourced directly from user-controlled $_POST['ba_cheetah_data']['post_id']. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disable the page builder layout on arbitrary posts by setting the _ba_cheetah_enabled post meta to false, including on posts owned by other users.
