Overview
Affected versions of this package are vulnerable to Use After Free via re-entrant execution and modification of the route set during iteration in RouteMap::UpdateActiveRoutes() in the CSS navigation component. An attacker can potentially cause heap corruption by causing the user to navigate to a crafted HTML page that defines a route with <script type="routemap"> and, in that route’s activate handler, adds another route (e.g., by injecting a second <script type="routemap">).
