Summary
Prototype Pollution in Dojox
Details

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];
