CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
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:
Graph.base64EncodeUnicode=function(a){return btoa(encodeURIComponent(a).replace(/%([0-9A-F]{2})/g,function(b,f){return String.fromCharCode(parseInt(f,16))}))};Graph.base64DecodeUnicode=function(a){return decodeURIComponent(Array.prototype.map.call(atob(a),function(b){return"%"+("00"+b.charCodeAt(0).toString(16)).slice(-2)}).join(""))};Graph.compressNode=function(a,b){a=mxUtils.getXml(a);return Graph.compress(b?a:Graph.zapGremlins(a))};
