Vulnerability Title
Online Scheduling and Appointment Booking System – Bookly <= 27.0 - Unauthenticated Price Manipulation via 'tips'
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to price manipulation via the 'tips' parameter in all versions up to, and including, 27.0. This is due to the plugin trusting a user-supplied input without server-side validation against the configured price. This makes it possible for unauthenticated attackers to submit a negative number to the 'tips' parameter, causing the total price to be reduced to zero.
