The vulnerability exists because `alg_wc_ev_generate_user_code()` generates the per-user activation secret using `wp_rand(100)` when the plugin's 'Encoding method' is set to 'hashids', producing only ~101 possible values (~7 bits of entropy); the resulting token is a reversible Hashids encoding with no cryptographic MAC, and the unauthenticated `verify()` handler — hooked to `init` at `PHP_INT_MAX` with no nonce check and no rate limiting — accepts and acts on the attacker-controlled `?alg_wc_ev_verify_email=` GET parameter directly. This makes it possible for unauthenticated attackers to gain authentication as any unverified WordPress account, including administrator-level accounts, by brute-forcing the trivially small activation code space via a forged verification URL. Exploitation requires that the 'Encoding method' setting be changed to 'hashids' (non-default), that the attacker recover or brute-force the Hashids salt (which defaults to an `md5(time())` value set at first initialization), and that the target account's email address remain unverified."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"wpcodefactory","product":"Customer Email Verification for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","lessThanOrEqual":"3.3.0","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-16T14:50:43.348176Z","id":"CVE-2026-104745","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@wordfence.com","type":"Secondary","description":[{"lang":"en","value":"CWE-269"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/emails-verification-for-woocommerce/tags/3.3.0/includes/alg-wc-ev-functions.php#L331","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/emails-verification-for-woocommerce/tags/3.3.0/includes/class-alg-wc-ev-core.php#L1258","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/emails-verification-for-woocommerce/tags/3.3.0/includes/class-alg-wc-ev-core.php#L498","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/emails-verification-for-woocommerce/tags/3.3.0/includes/class-alg-wc-ev-core.php#L784","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3744623%40emails-verification-for-woocommerce&new=3744623%40emails-verification-for-woocommerce","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6df7b3ed-a1e3-4df9-828e-95530661e27a?source=cve","source":"security@wordfence.com"}]}}]}
