# Salon Booking System WordPress plugin: staff role can grant administrator rights

The Salon Booking System WordPress plugin before 10.31.11 lets users with its custom salon staff role assign arbitrary capabilities to other accounts while editing a customer. An attacker holding that role can escalate any account, including their own, to administrator and take over the site.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or with `wp plugin get salon-booking-system --field=version` (unknown if the slug differs)
- Check whether any users hold the salon staff role in Users, or with `wp user list --role=<salon staff role slug>`

## Fix

- Update the Salon Booking System plugin to `10.31.11` or later
- Review administrator accounts and remove any added without cause; rotate passwords for accounts that held the staff role
