CVE-2025-31022Public exploitNetwork attack vector

Unauthenticated account takeover via permissive REST routes

Published Jun 9, 2025 · Updated Apr 28, 2026

Authentication bypass in PayU India before 3.8.8 allows remote attackers to take over any WordPress account through public REST APIs. The generate-user-token route returns a token for a hardcoded email, and get-shipping-cost passes the user ID resolved from an attacker-chosen email to update_cart_data, which calls wp_set_auth_cookie. No authentication is required; the resulting session can assume an administrator account.
