CVE-2026-103895

The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass in versions up to, and including, 5.5.8 via the mo by pass login() function. This is due to mo delay otp process() short-circuiting the authentication flow before password validation or the administrator intent gate (added in 5.5.6) can run, combined with the Delay OTP grace flag (mov last verified dttm) being stored as a user meta row keyed solely by target user ID with no binding to the originating session, cookie, IP address, or device. This makes it possible for unauthenticated attackers to authenticate as any WordPress user — including administrators — by submitting only a known username with the mo wp login intent=otp parameter and any non-empty password, thereby inheriting a legitimate user's open Delay OTP grace window without ever supplying correct credentials. Exploitation requires the site to have OTP-only login (wp login skip password=1, wp login skip password fallback=0) and Delay OTP Verification (wp login delay otp=1) enabled, and the target account must currently be within its configured Delay OTP interval.
