CVE-2024-54152: Angular Expressions - Remote Code Execution when using locals

An attacker can write a malicious expression that escapes the sandbox to execute arbitrary code on the system.

Example of vulnerable code:

const expressions = require("angular-expressions");
const result = expressions.compile("__proto__.constructor")({}, {});
// result should be undefined, however for versions <=1.4.2, it returns an object.

With a more complex (undisclosed) payload, one can get full access to Arbitrary code execution on the system.
