The advisory
The Salon Booking System WordPress plugin before 10.31.9 does not correctly verify the authenticity of REST API requests and discards WordPress core's nonce check for cookie-authenticated sessions across the whole REST API, allowing unauthenticated attackers who trick a logged-in administrator into clicking a crafted link to forge requests in that administrator's browser, up to creating a new administrator account.
