CVE-2023-3427

CWE-352Published: June 28, 2023· Updated: Jun 17, 2026

4.3

CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2023-3427 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
