The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
Sidebar.prototype.addFoldingHandler=function(a,c,f){var e=!1;if(!mxClient.IS_IE||8<=document.documentMode)a.style.backgroundImage="none"==c.style.display?"url('"+this.collapsedImage+"')":"url('"+this.expandedImage+"')";a.style.backgroundRepeat="no-repeat";a.style.backgroundPosition="0% 50%";mxEvent.addListener(a,"click",mxUtils.bind(this,function(g){if("none"==c.style.display){if(e)c.style.display="block";else if(e=!0,null!=f){a.style.cursor="wait";var d=a.innerHTML;a.innerHTML=mxResources.get("loading")+
