CVE-2026-89055: Customer Reviews for WooCommerce <= 5.120.0 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion via 'items[][media]' Parameter
The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to 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. Exploitation requires 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.

Event History
Frequently Asked Questions
Who is exposed to exploitation?
Sites using an affected version of the plugin are exposed if a public review-form link has been distributed to customers, such as by email. An attacker does not need a WordPress account or an authenticated session.
What does an attacker need to exploit the issue?
The attacker needs a public review-form link containing the 13-hex formId. That link exposes the nonce required to reach the affected handler.
What can be deleted through exploitation?
An attacker can permanently delete arbitrary Media Library attachments by supplying their IDs in the items[][media] parameter of a review that is subsequently trashed and purged. This can include administrator-owned product images, logos, and documents.
What can be done if patching is not immediately possible?
The available information identifies public review-form links as the prerequisite for exploitation. Limiting exposure of those links can reduce access to the required formId and nonce, but the data does not provide a complete mitigation.
