Details

The Wholesale for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.5. This is due to the save_requests_meta() function applying only sanitize_text_field() to the user_role_set POST parameter before passing it directly to WP_User::add_role(), with no allowlist validation against permitted wholesale roles and no capability check such as current_user_can('promote_users') or current_user_can('manage_options'). This makes it possible for authenticated attackers with author-level access and above to escalate their privileges to administrator by supplying administrator as the user_role_set value in a crafted request. The function is gated only by a nonce (request_user_role_nonce) that is rendered in the meta box on the wwp_requests post edit screen; because the post type is registered with capability_type => 'post', any author-level user who has authored a wwp_requests post — such as one created via the wholesale registration form — can access this nonce and submit the role-assignment request.

Severity
