Description

In affected versions of dojox (NPM package), the jqMix method is vulnerable to Prototype Pollution. Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. This has been patched in versions 1.11.10, 1.12.8, 1.13.7, 1.14.6, 1.15.3 and 1.16.2
