Affected packages
• npm aurelia-path: < 1.1.7 → fixed in 1.1.7
Description
Impact
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`
Patches
The problem should be patched in version `1.1.7`. Any version earlier than this is vulnerable.
Workarounds
A partial work around is to free the Object prototype:
```ts
Object.freeze(Object.prototype)
```
