Vulnerability from github
The Dojox jQuery wrapper jqMix mixin method is vulnerable to Prototype Pollution.
Affected Area:
//https://github.com/dojo/dojox/blob/master/jq.js#L442
var tobj = {};
for(var x in props){
// the "tobj" condition avoid copying properties in "props"
// inherited from Object.prototype. For example, if obj has a custom
// toString() method, don't overwrite it with the toString() method
// that props inherited from Object.prototype
if((tobj[x] === undefined || tobj[x] != props[x]) && props[x] !== undefined && obj != props[x]){
if(dojo.isObject(obj[x]) && dojo.isObject(props[x])){
if(dojo.isArray(props[x])){
obj[x] = props[x];
}else{
obj[x] = jqMix(obj[x], props[x]);
}
}else{
obj[x] = props[x];
