The 10Web Booster WordPress plugin before 2.33.5 does not correctly validate an access token on an unauthenticated request handler and does not escape attacker-supplied stylesheet content before rendering it into the page head, allowing an unauthenticated attacker to store markup that executes as JavaScript in the browser of anonymous visitors to an affected page.
