CVE-2026-12144— Wholesale for WooCommerce <= 2.0.5 - Authenticated (Author+) Privilege Escalation via 'user_role_set' Parameter

Wholesale for WooCommerce <= 2.0.5 - Authenticated (Author+) Privilege Escalation via 'user_role_set' Parameter

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.

特权管理不恰当

WordPress Wholesale for WooCommerce 权限许可和访问控制问题漏洞

WordPress Wholesale for WooCommerce是WordPress基金会的一款电商批发功能插件。 WordPress Wholesale for WooCommerce 2.0.5及之前版本存在权限许可和访问控制问题漏洞，该漏洞源于`save_requests_meta()`函数仅对`user_role_set` POST参数应用清理，未进行白名单验证和权限检查，可能导致已认证的攻击者（作者级别及以上）将权限提升至管理员。
