Customer Reviews for WooCommerce に脆弱性 — CVE-2026-89055
いま何をすべきか
Customer Reviews for WooCommerce を 5.121.0 以降に更新してください。
影響を受けるバージョン
- 5.120.0 以下のすべて
対象: プラグイン「Customer Reviews for WooCommerce」(customer-reviews-woocommerce)
何が起きるのか
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.
