Arbitrary Price Manipulation in Booking Package WordPress Plugin

Publication date: 2026-08-26

Last updated on: 2026-08-26

Assigner: WPScan

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.

Executive Summary

This vulnerability affects the Booking Package WordPress plugin before version 1.7.25. It allows an unauthenticated attacker to manipulate the payment amount server-side by supplying arbitrary values in their request. Instead of validating the payment against the actual service price, the plugin derives the expected charge from the attacker-controlled input, enabling them to pay a fraction of the real price.

Impact Analysis

If you use the affected Booking Package plugin, an attacker could exploit this to pay less than the actual price for services. This could lead to financial losses for service providers using the plugin. Additionally, it may undermine trust in payment processing and cause disputes over transactions.

Mitigation Strategies

Update the Booking Package WordPress plugin to version 1.7.25 or later to ensure proper server-side validation of payment amounts against stored service prices.
