Missing authorization in Apache Wicket. org.apache.wicket.core.request.handler.ListenerRequestHandler invokes an IRequestListener only when org.apache.wicket.Component#canCallListener() allows it, and that method is isEnabledInHierarchy() && isVisibleInHierarchy(). The visibility half reads a flag that carries the outcome of IAuthorizationStrategy#isActionAuthorized() for the Component.RENDER action, and that flag is written in one place only, Component#configure(), during the render phase. A listener URL built by a subclass of org.apache.wicket.core.request.mapper.AbstractBookmarkableMapper carries the page identifier and the component path in a single parameter, and the page identifier may be empty. When it is, a new page instance is constructed, PageProvider#wasExpired() is false because no identifier was supplied, and PageAndComponentProvider#getComponent() finds the component directly on the new instance, so neither a render pass nor Component#configure() runs before the listener is invoked. The flag therefore still holds its constructor default, the component counts as visible, and the listener of a component the authorization strategy denied RENDER for is executed. The same…
