Name of the Vulnerable Software and Affected Versions The Salon Booking System plugin for WordPress versions up to, and including, 8.4.6

Description The issue is due to missing or incorrect nonce validation on the save customer function, making it possible for unauthenticated attackers to change the admin role to customer or change the user meta to arbitrary values via a forged request. This can happen if attackers can trick a site administrator into performing an action such as clicking on a link.

Recommendations For versions up to, and including, 8.4.6, update to a version that includes the fix for the missing or incorrect nonce validation on the save customer function. As a temporary workaround, consider restricting access to the save customer function until a patch is available.
