CVE-2026-8760
CriticalSummary
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, allowing attackers to brute-force the 6-digit OTP without a time limit.
Risk Assessment
Attackers can gain access to user accounts, including administrators, leading to full site compromise. This poses a serious threat to data security and system integrity.
Recommendation
It is recommended to update the plugin to the latest version to eliminate this vulnerability. Additionally, implementing extra security measures, such as limiting login attempts, is advisable.

Original NVD description (English source)
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.
