CVE-2026-8760
Received Received - Intake
Authentication Bypass in WordPress Login with OTP Plugin

Publication date: 2026-05-27

Last updated on: 2026-05-27

Assigner: Wordfence

Description
The Login with OTP plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.6. This is due to an incomplete fix for CVE-2024-11178: the rate-limit/lockout check added to `otpl_login_action()` was placed only inside the OTP-generation branch and is never evaluated on the OTP-validation branch, and the generated 6-digit OTP additionally has no expiration. This makes it possible for unauthenticated attackers to brute-force the 900,000-value OTP space for any user account (including administrators) and obtain a valid `wp_set_auth_cookie()` session, leading to full site compromise.

AI Powered Q&A
Can you explain this vulnerability to me?

The Login with OTP plugin for WordPress, up to and including version 1.6, has an authentication bypass vulnerability. This occurs because a previous fix for a similar issue (CVE-2024-11178) was incomplete: the rate-limit and lockout checks were only applied during OTP generation, not during OTP validation. Additionally, the 6-digit OTP generated does not expire. As a result, unauthenticated attackers can brute-force the 900,000 possible OTP values for any user account, including administrators, and gain a valid authentication session, leading to full site compromise.


How can this vulnerability impact me? :

This vulnerability allows attackers to bypass authentication without any privileges or user interaction. By brute-forcing the OTP, attackers can log in as any user, including administrators, and gain full control over the WordPress site. This can lead to unauthorized access, data theft, site defacement, or complete takeover of the website.
