The Offsprout Page Builder plugin for WordPress is vulnerable to Privilege Escalation due to improper authorization placed on the permission_callback() function in versions 2.2.1 to 2.15.2. This makes it possible for authenticated attackers, with Contributor-level access and above, to read, create, update or delete any user meta, including flipping their own wp_capabilities to administrator and fully escalate their privileges.
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
