Unauthenticated price manipulation via insufficient booking validation
Published Apr 24, 2024 · Updated Apr 28, 2026
Improper input validation in Repute InfoSystems BookingPress 1.0.74 and earlier allows remote attackers to alter appointment prices. The bookingpress_confirm_booking function insufficiently validates booking price data before confirming an appointment, allowing the submitted price to override the intended amount. No account or user interaction is required, and successful requests can create appointments at attacker-chosen prices.
