Technical details
The plugin's HTML optimization routine does not properly restrict its processing to stylesheet content, allowing it to delete attribute-closing markup. Combined with unescaped output of comment author data, an unauthenticated user can inject event-handler attributes into the rendered page. The vulnerability is stored (persisted in comments) and executes in the browser of any visitor when the optimization feature is enabled.
