Unauthenticated price manipulation via unchecked cart data
Published Aug 15, 2026 · Updated Aug 15, 2026
Improper input validation in Pinpoint Booking System 2.9.9.6.8 and earlier allows remote attackers to set prices via cart_data. The unauthenticated dopbsp_woocommerce_add_to_cart AJAX update handler stores price_total from attacker-controlled cart_data, and the totals callback passes that value to set_price without recalculating it from calendar settings. Any bookable product linked to a booking calendar can therefore be purchased at a self-chosen price without an account.
