# serverless-plugin-cloudformation-cross-region-variables 

This plugin supports using [coudformation stack outputs](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/outputs-section-structure.html) from stacks in different regions.

Adds new variable syntax to serverless formatted as such `${cfcr:Region:StackName:OutputKey}`

Also now allow use of the variable syntax `${ssmcr:Region:ParamPath}` for cross region SSM parameters or `${ssmcr:Region:ParamPath~true}` to decrypt secure strings values returned.

## Usage

```yaml

custom:
  # We have another stack we want to know about in us-east-1
  myServiceEndpoint: ${cfcr:us-east-1:other-stack-name-${opt:stage}:ServiceEndpoint}

plugins:
  - serverless-plugin-cloudformation-cross-region-variables 
```


## Attributions

This plugin used [serverless-plugin-git-variables](https://github.com/jacob-meacham/serverless-plugin-git-variables) as a base.

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.
