Root Cause Analysis

I was unable to find a patch for this vulnerability, and the original repository is not accessible. However, based on the vulnerability description, the issue lies within the addFileDepend function in the util-deps.js file of the magix-combine-ex package. The vulnerability is a prototype pollution, which occurs when user-controlled input is used to modify the prototype of a JavaScript object. This can lead to denial of service or other security issues.

After analyzing the code of addFileDepend from a public copy of the package, I identified the vulnerable code. The function iterates over the properties of a depend object and assigns them to a file.depend object. If an attacker provides a crafted depend object with a __proto__ property, they can pollute the Object.prototype.
