# Salon Booking System WordPress plugin: predictable API tokens let attackers impersonate staff

The Salon Booking System WordPress plugin before 10.31.9 derives its booking-API access tokens from a hardcoded value and the issue time instead of a secure random source. An attacker who can work out when a staff or administrator token was issued can compute a valid token and act on the booking API as that user, including an administrator.

_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 Plugins screen, or run `wp plugin get salon-booking-system --field=version` with WP-CLI, and confirm it is `10.31.9` or later.
- unknown for any further check the sources give

## Fix

- Update the Salon Booking System plugin to `10.31.9` or later.
- After updating, consider rotating booking-API tokens for staff and administrator accounts, since tokens issued before the fix may have been predictable.

## From the sources

The Salon Booking System  WordPress plugin before 10.31.9 does not generate its booking-API access tokens from a secure random source, instead deriving them from a value hardcoded in the Salon Booking System  WordPress plugin before 10.31.9 and the second at which a token was issued. An attacker able to constrain when a staff or administrator token was issued can compute a valid token and access the booking API as that user, including an administrator.
