Prototype pollution via jqMix __proto__ mixing
Published Mar 10, 2020 · Updated Aug 4, 2024
Prototype Pollution in Dojox (NPM package) allows attackers to alter JavaScript object prototypes via crafted jqMix input. The jqMix mixin recursively copies properties and accepts the special proto key, assigning attacker-controlled values into the destination object and thereby polluting its prototype. The vulnerable path requires a consuming application to pass attacker-influenced properties; resulting behavior changes are application-dependent, and direct code execution is not established by the advisory.
