The vulnerability exists because the OTP rate-limit attempt counter in `process_otp_form` is keyed exclusively on the attacker-controlled `xoo_ml_user_ip_data` cookie's `ip_address` field, allowing unlimited counter resets by simply rotating the cookie, while the OTP itself is generated with PHP's non-cryptographic `rand()` function over a default space of only 9,000 possible values (1000–9999), and both the OTP issuance endpoint (`xoo_ml_login_with_otp`) and verification endpoint (`xoo_ml_otp_form_submit`) are registered as unauthenticated `wp_ajax_nopriv` actions with no nonce or capability checks. This makes it possible for unauthenticated attackers to brute-force the OTP for any registered account and obtain a full WordPress authentication session — including for administrator accounts — via `wp_set_auth_cookie()` in `login_user_with_otp()`. Exploitation requires the attacker to know the target user's registered phone number, which is used to trigger OTP issuance via the unauthenticated `xoo_ml_login_with_otp` endpoint."}],"title":"OTP Login & Register Woocommerce <= 2.7.2 - Unauthenticated Authentication Bypass via Brute Force","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4bd4b379-6d7d-4cfe-bb16-a931c5d68d02?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/mobile-login-woocommerce/tags/2.7.2/includes/class-xoo-ml-verification.php#L472"},{"url":"https://plugins.trac.wordpress.org/browser/mobile-login-woocommerce/tags/2.7.2/includes/class-xoo-ml-verification.php#L84"},{"url":"https://plugins.trac.wordpress.org/browser/mobile-login-woocommerce/tags/2.7.2/includes/class-xoo-ml-otp-handler.php#L155"},{"url":"https://plugins.trac.wordpress.org/browser/mobile-login-woocommerce/tags/2.7.2/includes/class-xoo-ml-geolocation.php#L24"},{"url":"https://plugins.trac.wordpress.org/browser/mobile-login-woocommerce/tags/2.7.2/includes/class-xoo-ml-otp-handler.php#L24"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3639216%40mobile-login-woocommerce%2Ftrunk%2Fincludes%2Fclass-xoo-ml-otp-handler.php&old=3419316%40mobile-login-woocommerce%2Ftrunk%2Fincludes%2Fclass-xoo-ml-otp-handler.php&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"d4ngvn"}],"timeline":[{"time":"2026-09-01T16:51:16.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-10T14:39:11.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-12215","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-11T13:09:22.330389Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-11T13:46:23.712Z"}}]}}
