CVE-2026-12144
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
The Wholesale for WooCommerce plugin for WordPress up to version 2.0.5 allows privilege escalation. The `save_requests_meta()` function only applies `sanitize_text_field()` to the `user_role_set` parameter before passing it to `WP_User::add_role()`, without validating allowed roles. Authenticated attackers with author access can escalate their privileges to administrator.
Risk Assessment
An attacker can gain unauthorized administrative access, leading to full site control and potential data theft.
Recommendation
Update the plugin to the latest version. Restrict access to role assignment functions to trusted users only.

Original NVD description (English source)
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.
