{"id":"CVE-2026-109236","state":"PUBLISHED","title":"Customer Email Verification for WooCommerce <= 2.8.2 - Unauthenticated Authentication Bypass via Predictable Email-Verification Token to 'cusomer_email_verify' Parameter","description":"The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via a Predictable Email-Verification Token in all versions up to, and including, 2.8.2. This is due to the `authenticate_user_by_email_link()` function — hooked on the `wp` action and triggered by the `cusomer_email_verify` GET parameter — 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 — or to flip an existing account's `customer_email_verified` meta to verified — 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.","publishedAt":"2026-10-28T05:33:31.213Z","updatedAt":"2026-10-28T16:10:40.810Z","severity":{"score":4.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["zorem Customer Email Verification for WooCommerce"],"affected":[{"vendor":"zorem","product":"Customer Email Verification for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.8.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a2e9fa74-5501-4429-a500-1d4199571a34?source=cve","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.2/includes/class-wc-customer-email-verification-signup.php#L616","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.2/includes/class-wc-customer-email-verification-signup.php#L580","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.2/includes/class-wc-customer-email-verification-signup.php#L274","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.2/includes/class-wc-customer-email-verification-signup.php#L151","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.2/includes/class-wc-customer-email-verification-signup.php#L119","https://wordpress.org/plugins/customer-email-verification-for-woocommerce/#developers","https://plugins.trac.wordpress.org/browser/customer-email-verification-for-woocommerce/tags/2.8.3/includes/class-wc-customer-email-verification-signup.php"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/109xxx/CVE-2026-109236.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-109236","state":"PUBLISHED","datePublished":"2026-10-28T05:33:31.213Z","dateUpdated":"2026-10-28T16:10:40.810Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-12T14:04:30.464Z"},"containers":{"cna":{"title":"Customer Email Verification for WooCommerce <= 2.8.2 - Unauthenticated Authentication Bypass via Predictable Email-Verification Token to 'cusomer_email_verify' Parameter","descriptions":[{"lang":"en","value":"The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via a Predictable Email-Verification Token in all versions up to, and including, 2.8.2.
