Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Salon Booking System Salon booking system allows SQL Injection.This issue affects Salon booking system: from n/a through 10.7.

The Salon booking system plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on several functions hooked into admin_init in all versions up to, and including, 9.9. This makes it possible for authenticated attackers with subscriber access or higher to modify plugin settings and view discount codes intended for other users.

The Salon Booking System plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.4.6. This is due to missing or incorrect nonce validation on the 'save_customer' function. This makes it possible for unauthenticated attackers to change the admin role to customer or change the user meta to arbitrary values via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

Cross-site scripting vulnerability in Salon booking system versions prior to 7.9 allows a remote unauthenticated attacker to inject an arbitrary script.

The Salon booking system Free and Pro WordPress plugins before 7.6.3 do not have proper authorisation in some of its endpoints, which could allow customers to access all bookings and other customer's data

The Salon booking system Free and pro WordPress plugins before 7.6.3 do not have proper authorisation when searching bookings, allowing any unauthenticated users to search other's booking, as well as retrieve sensitive information about the bookings, such as the full name, email and phone number of the person who booked it.

The Salon booking system WordPress plugin before 6.3.1 does not properly sanitise and escape the First Name field when booking an appointment, allowing low privilege users such as subscriber to set JavaScript in them, leading to a Stored Cross-Site Scripting (XSS) vulnerability. The Payload will then be triggered when an admin visits the "Calendar" page and the malicious script is executed in the admin context.
