Check if the Salon Booking System plugin version is 10.30.33 or lower. Look for unauthorized changes in booking totals or suspicious AJAX requests to booking-modification endpoints.

Impact Analysis

An attacker could tamper with booking totals, leading to incorrect financial records, disputes with customers, or potential fraud. This could disrupt business operations and damage trust in the booking system.

This vulnerability may impact compliance by allowing unauthorized modifications to financial or personal data, violating integrity and access control requirements in GDPR and HIPAA. It could lead to data breaches or inaccurate records, risking regulatory penalties.
