Description

The Storegrowth Sales Booster plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 2.1.0. This is due to a missing capability check on the bogo_category_msg_create() AJAX handler, which is registered for both authenticated (wp_ajax_) and unauthenticated (wp_ajax_nopriv_) users and only validates a nonce ('ajd_protected') that is emitted publicly via wp_localize_script() on every frontend page through front_scripts() . This makes it possible for unauthenticated attackers to modify the plugin's BOGO category-message configuration stored in the spsg_bogo_general_settings option by reading the nonce from any public page and POSTing attacker-controlled data to admin-ajax.

• CWE-862Missing AuthorizationThe product does not perform an authorization check when an actor attempts to access a resource or perform an action.
