CVE-2026-2519

Published: Apr 9, 2026

Modified: Apr 13, 2026

PUBLISHED

CVSS v3.1

5.3

MEDIUM

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.
