This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

The Wholesale Market plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.2.2 via the ced_wholesale_request_send AJAX action. The ced_wholesale_request_send_callback() handler only verifies a nonce (which is exposed to any authenticated user through wp_localize_script on the frontend) and that the caller has a positive user ID, then calls WP_User::add_role() with the client-supplied role_required POST parameter without restricting the value to an allowlist of wholesale roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator when the site administrator has enabled the 'Assigning requested role directly' option.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
