What is CVE-2026-15823?
CVE-2026-15823 is a medium-severity missing authorization vulnerability in Builderall for WordPress, published on 10 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-862
