What is CVE-2026-12144?
CVE-2026-12144 is a high-severity vulnerability in saadiqbal Wholesale for WooCommerce, published on 29 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
