Description An unauthenticated request handler fails to correctly validate access tokens and does not escape stylesheet content provided by users before rendering it into the page head. This allows an unauthenticated attacker to store markup that executes as JavaScript in the browsers of anonymous visitors to an affected page, leading to a stored cross-site scripting (XSS) condition.
