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.

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.

		Transform & migrate JSON data to new schemas, with type-safe validation using Zod.
		A fast, type-safe JSON migration tool with Zod schema validation.

		Useful for local JSON that evolves over time, like app settings, saved documents, or cached data.
		## Features

		- Type-safe migrations for JSON with full TypeScript inference
		- Zod schema validation at every step
		- Fluent builder API for migration chains
		- Automatic version tracking
		- Zero runtime dependencies (only Zod as peer)

		## Quick Start

		## What is a migration?

		A migration is a step that transforms your data from one version to the next.
		When your data structure changes over time, migrations let you upgrade old
		data to match your current format.

		## Example

		Imagine you have user profiles stored as JSON, saved to a file.

		Originally, you stored a single `name` field.

		Now, in your latest app, you want to split it into `firstName` and `lastName`.

		You could write `if` statements, but this gets risky as more changes come along.

		So how can you safely update the state?
