Salon Booking System < 10.31.9 - Unauthenticated Salon REST API Access via Predictable Access-Token

Description

The plugin does not generate its booking-API access tokens from a secure random source, instead deriving them from a value hardcoded in the plugin 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.
