What the vulnerability does
01Description
The Bricks theme for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.9.6.1. This is due to insufficient validation checks placed on the create_autosave AJAX function. This makes it possible for authenticated attackers, with contributor-level access and above, to execute arbitrary PHP code with elevated (administrator-level) privileges. NOTE: Successful exploitation requires (1) the Bricks Builder to be enabled for posts (2) Builder access to be enabled for contributor-level users, and (3) "Code Execution" to be enabled for administrator-level users within the theme's settings.
