WordPress Customer Reviews for WooCommerce Plugin Authorization Bypass Vulnerability

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to an authorization bypass in all versions up to and including 5.120.0.

This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to permanently delete arbitrary attachments from the Media Library — including administrator-owned product images, logos, and documents — by injecting their IDs into a review that is later trashed and purged.

• Affected versions: all versions up to and including 5.120.0
• Attack requirement: a public review-form link (a 13-hex formId distributed to customers via e-mail), which exposes the nonce needed to reach the handler without any WordPress account or session
• Impact: permanent deletion of arbitrary Media Library attachments
