On KEV
Description
The Booking Package WordPress plugin before 1.7.25 does not validate the payment amount server-side against the stored service price, deriving the expected charge from attacker-supplied request values instead, so an unauthenticated attacker can pay an arbitrary fraction of a service's real price.
