## Affected

- Unknown Booking Package: fixed in 1.7.25

## 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.

## What to do

- Check your stack: if you ship or depend on Unknown Booking Package, upgrade to a fixed version (1.7.25) per the references below.
