# Typed JSON Parse

## Summary

This package overrides the default `JSON.parse()` types with a JSON parser built in TypeScript types, meaning if you put a valid string literal in, you will get the actual type it represents.

```typescript
const value = JSON.parse('{ "Hello": "NPM!", "foo": [true, 123] }');

// With the actual type of value being:
const value: {
  Hello: string,
  foo: (boolean | number)[]
}
```

## But its useless

Correct. Since you have the literal string, just use the contents in JS/TS. As a tiny bonus, any non-literal string produces `unknown` instead of `any`.

## So, why?

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
