CVE-2026-9242Network attack vector

Unauthenticated account takeover via forged PayPal IPN

Published Jun 27, 2026 · Updated Jun 27, 2026

Authentication bypass in Metagauss RegistrationMagic 6.0.8.6 and earlier allows remote attackers to impersonate any WordPress user. The unauthenticated PayPal IPN callback writes attacker-controlled payment_status and custom user_id values to a payment log before validating the notification. A payment log entry and its valid security hash are required; the success return path then issues authentication cookies, including for administrators.
