CVE-2022-38134Network attack vector

Review disclosure via unprotected AJAX actions

Published Sep 23, 2022 · Updated Apr 28, 2026

Broken access control in Customer Reviews for WooCommerce 5.3.5 and earlier allows remote authenticated users to invoke restricted AJAX actions. Several AJAX handlers omit nonce and capability checks, exposing administrator-only operations including review export. Subscriber-level access is sufficient; the bounded consequence is disclosure of review data stored by the site.
