CVE-2026-14245: miniOrange OTP Login authentication bypass in Ultimate Member reset hook

CVE-2026-14245 · Severity: critical · CVSS 9.8 · Published 2026-07-09

Vendors: miniOrange.

Executive brief

The miniOrange OTP Login plugin for WordPress, which provides one-time password security for logins and password resets, contains a flaw that allows attackers to bypass security checks. By exploiting this vulnerability, an unauthenticated attacker can take over any user account, including administrator accounts, by obtaining a valid password reset link without needing the required security code. This could lead to a total compromise of the website, including the theft of customer data or the modification of site content.

Technical details

The vulnerability exists in the `um_reset_password_process_hook()` function due to a lack of server-side verification that an OTP validation step was successfully completed. The plugin relies on a public `form_nonce` exposed via the `moumprvar` JavaScript object and fails to bind the password reset request to a validated session. An unauthenticated attacker can provide an arbitrary username via the `username_b` parameter to trigger a password reset. The server then returns a valid password-reset URL in a 302 redirect Location header, allowing the attacker to reset the administrator's password and gain full account access. This exploit requires the Ultimate Member Password Reset Form integration to be enabled and the plugin to be configured for something other than phone-only resets.
