{"id":"CVE-2026-85984","state":"PUBLISHED","title":"miniOrange OTP Login, Verification and SMS Notifications <= 5.5.5 - Unauthenticated Authentication Bypass via 'mo_wp_login_intent' Parameter","description":"The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass via the mo_wp_login_intent parameter in all versions up to, and including, 5.5.5. This is due to a missing password-intent guard in the skip_pass_fallback-enabled configuration branch of the mo_by_pass_login() function, which treats administrator role membership alone as sufficient authentication whenever the unauthenticated, unverified POST parameter mo_wp_login_intent is submitted with the value otp, causing mo_get_user() to skip wp_authenticate_username_password() and resolve a WP_User purely from a username lookup. This makes it possible for unauthenticated attackers to log in as any existing administrator account by supplying only a known username and an empty password alongside mo_wp_login_intent=otp, with no password or OTP verification required. Exploitation is conditional on a site administrator having simultaneously enabled the following plugin options: WP Login OTP, Login with Only OTP, Allow Users to Login with Username and Password, and Admin OTP Bypass.","publishedAt":"2026-09-26T17:28:59.138Z","updatedAt":"2026-09-26T22:51:17.200Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["cyberlord92 miniOrange OTP Login, Verification and SMS Notifications"],"affected":[{"vendor":"cyberlord92","product":"miniOrange OTP Login, Verification and SMS Notifications","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.5.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/2895f0c2-41b6-4b11-9865-3bded4402aa9?source=cve","https://plugins.trac.wordpress.org/browser/miniorange-otp-verification/tags/5.5.5/views/forms/mowploginform.php#L134","https://plugins.trac.wordpress.org/browser/miniorange-otp-verification/tags/5.5.5/includes/js/loginform.js#L176","https://plugins.trac.wordpress.org/changeset/3687601/miniorange-otp-verification"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85984.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85984","state":"PUBLISHED","datePublished":"2026-09-26T17:28:59.138Z","dateUpdated":"2026-09-26T22:51:17.200Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-04T19:17:29.094Z"},"containers":{"cna":{"title":"miniOrange OTP Login, Verification and SMS Notifications <= 5.5.5 - Unauthenticated Authentication Bypass via 'mo_wp_login_intent' Parameter","descriptions":[{"lang":"en","value":"The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass via the mo_wp_login_intent parameter in all versions up to, and including, 5.5.5.
