CVE-2025-12788Network attack vector

Unauthenticated payment bypass via unverified confirmation data

Published Nov 11, 2025 · Updated Nov 11, 2025

Payment verification bypass in Themefic Hydra Booking 1.1.27 and earlier allows remote attackers to confirm unpaid bookings as paid. The tfhb_meeting_paypal_payment_confirmation_callback function trusts client-controlled confirmation data without validating it through PayPal's API. No account is required; successful requests alter booking payment state without a PayPal transaction, affecting booking integrity rather than confidentiality or availability.
