Summary
aurelia-path is part of the Aurelia platform and contains utilities for path manipulation. There is a prototype pollution vulnerability in aurelia-path before version 1.1.7. The vulnerability exposes Aurelia application that uses `aurelia-path` package to parse a string. The majority of this will be Aurelia applications that employ the `aurelia-router` package. An example is this could allow an attacker to change the prototype of base object class `Object` by tricking an application to parse the following URL: `https://aurelia.io/blog/?__proto__[asdf]=asdf`. The problem is patched in version `1.1.7`.
