CVE-2026-15823: CWE-862 Missing Authorization in builderall Builderall for WordPress
Description
Builderall Cheetah For WordPress plugin versions up to 3.0.2 contains a missing authorization vulnerability. The wp_ajax_ba_cheetah_disable AJAX handler lacks capability and nonce verification, allowing authenticated users with Subscriber-level access or higher to disable the page builder layout on arbitrary posts, including those owned by other users. This is achieved by modifying the _ba_cheetah_enabled post meta to false via user-controlled input.

Technical Analysis
CVE-2026-15823 describes a missing authorization vulnerability (CWE-862) in the Builderall Cheetah For WordPress plugin up to version 3.0.2. The vulnerability arises because the AJAX handler wp_ajax_ba_cheetah_disable does not perform capability or nonce checks, and it directly uses the post_id from user-supplied POST data. This allows authenticated users with low privileges (Subscriber and above) to disable the page builder layout on posts they do not own by setting the _ba_cheetah_enabled meta key to false.
Potential Impact
The vulnerability allows authenticated attackers with Subscriber-level privileges or higher to modify post metadata on arbitrary posts, disabling the page builder layout. This results in integrity impact by unauthorized modification of content presentation but does not affect confidentiality or availability. The CVSS score is 4.3 (medium severity), reflecting low complexity and limited impact confined to integrity.
Mitigation Recommendations
No official patch or fix is currently documented. Users should monitor the vendor advisory for updates. Until a fix is available, restrict user roles to trusted users only and consider disabling or limiting access to the affected AJAX functionality if possible. Implementing custom capability checks or nonce verification in the AJAX handler can mitigate the risk.
