{"id":"CVE-2026-85984","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-85984","summary":"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,…","details":"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.","published":"2026-09-26T18:16:31.010","modified":"2026-09-26T18:16:31.010","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/miniorange-otp-verification/tags/5.5.5/includes/js/loginform.js#L176"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/miniorange-otp-verification/tags/5.5.5/views/forms/mowploginform.php#L134"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3687601/miniorange-otp-verification"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2895f0c2-41b6-4b11-9865-3bded4402aa9?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-26T18:16:31.010"}}
