Unauthenticated payment bypass via unverified notifications
Published Aug 7, 2026 · Updated Aug 7, 2026
Payment verification failure in ThimPress WP Events Manager before 2.2.5 allows remote attackers to mark bookings as paid. The PayPal IPN handler trusts an attacker-controlled booking identifier after PayPal verifies an unrelated payment, without checking the receiver or amount. No account is required; a pending booking identifier is enough to mark any booking as paid without funds reaching the merchant.
