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.","state":0,"publishedAt":"2026-10-28T05:33:31.213+00:00","modifiedAt":"2026-10-28T16:10:40.81+00:00","affected":[{"ecosystem":"Vendor product","name":"Customer Email Verification for WooCommerce","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"zorem\",\n                    \"product\": \"Customer Email Verification for WooCommerce\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.8.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","score":4.8,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109236","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109236","identifiers":["CVE-2026-109236"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
