What is CVE-2026-89055?
CVE-2026-89055 is a critical missing authorization vulnerability in ivole Customer Reviews for WooCommerce, published on 25 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-862
