## License

[MIT](https://github.com/ajv-validator/ajv-formats/blob/master/LICENSE)


The ajv-draft-04 package is an extension for AJV, a popular JSON schema validator, enabling it to validate schemas written according to the JSON Schema Draft 04 specification. This package allows users to leverage AJV's fast validation capabilities while ensuring compatibility with older schema versions.

This code demonstrates how to create a new AJV instance compatible with Draft 04 schemas, compile a schema, and validate a JSON object against it. It checks if the object meets the schema requirements (in this case, having a name as a string and an age as a number not less than 18), and prints whether the object is valid or not.

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.
