## Setup

```
npm install -g corsproxy
corsproxy
# with custom port: CORSPROXY_PORT=1234 corsproxy
# with custom host: CORSPROXY_HOST=localhost corsproxy
# with debug server: DEBUG=1 corsproxy
# with custom payload max bytes set to 10MB (1MB by default): CORSPROXY_MAX_PAYLOAD=10485760 corsproxy
```

### Docker

It is also possible to run the cors proxy in a docker container:

```
# Build image
docker build -t corsproxy .

# Run container
docker run -p 1337:1337 --name corsproxy -d corsproxy
```

## Usage

The cors proxy will start at http://localhost:1337.
To access another domain, use the domain name (including port) as the first folder, e.g.

- http://localhost:1337/localhost:3000/sign_in
- http://localhost:1337/my.domain.com/path/to/resource
- etc etc

By default the cors proxy will only answer requests sent to localhost. To use another domain (e.g. machine name) set an enviroment variable CORSPROXY_HOST to the required value before launching.

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.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
