CVE-2026-67363Network attack vector

Unauthorized purchases via client-controlled payment total

Published Aug 19, 2026 · Updated Aug 21, 2026

Payment tampering in Balbooa Forms before 2.4.3.2 allows remote attackers to buy priced items for arbitrary amounts via crafted payment requests. The stripeCharges and payAuthorize endpoints trust a client-supplied total and related line-item fields, then send those values to the payment gateway instead of recomputing them from the form's configured prices. No authentication or CSRF validation is enforced on either endpoint, so any internet-reachable site exposing these payment forms can be used to underpay orders and falsify quantities or shipping details.
