This is due to the `authenticate_user_by_email_link()` function \u2014 hooked on the `wp` action and triggered by the `cusomer_email_verify` GET parameter \u2014 lacking any capability check or nonce verification, while the `secret_code` it validates is generated as `md5(email . time())` and the `verify_otp_nonce` required to trigger token issuance via the `wp_ajax_nopriv_resend_otp` handler is emitted to every front-end visitor through `wp_localize_script`. This makes it possible for unauthenticated attackers to log in as a newly created, verified WooCommerce customer bound to an arbitrary email address \u2014 or to flip an existing account's `customer_email_verified` meta to verified \u2014 fully bypassing the plugin's core email-verification control. Exploitation requires the `cev_user_log` table to contain a `password` column, which is absent from the fresh-install schema shipped in version 2.8.2 but is present on sites upgraded from an older version where that column was defined."}], "lastModified": "2026-10-28T17:17:33.647", "sourceIdentifier": "security@wordfence.com"}
