CVE-2026-8760Network attack vector

Unauthenticated account takeover via unthrottled OTP validation

Published May 27, 2026 · Updated May 27, 2026

Authentication bypass in WP-EXPERTS.IN Login with OTP 1.6 and earlier allows remote attackers to take over WordPress accounts. In otpl_login_action(), the OTP-validation branch skips the rate-limit and lockout check, while six-digit OTPs do not expire. No authentication or user interaction is required; guessing an account's OTP yields a WordPress authentication cookie with that account's privileges.
