Joomla Extension - balbooa.com - Pre-auth Payment Amount Tampering in Balbooa Forms < 2.4.3.2 - The stripeCharges and payAuthorize endpoints accept the charge total from a client-controlled request parameter and forward it to the payment gateway without recomputing it from the form's configured product prices. Neither endpoint enforces authentication or CSRF checks. An unauthenticated attacker can purchase any priced item for an arbitrary amount (e.g., $0.01), and can additionally forge line items, quantities, and shipping.
