actions / checkout

TL;DR

Software engineers often need to access specific versions of code in their repositories during automated workflows. The GitHub Actions 'checkout' action allows users to check out their repository code into the $GITHUB_WORKSPACE environment, with options to fetch a single commit or the entire history.

✦ Why It Matters

Engineers can streamline their CI/CD processes by effectively using the GitHub Actions 'checkout' action to manage code versions.

Key Takeaways

Review the new default settings for fork pull requests in GitHub Actions.
Enable allow-unsafe-pr-checkout only after assessing risks.
Update your workflows to use the latest version of actions/checkout.
Ensure proper permissions for GITHUB_TOKEN in your workflows.

How It Works

The checkout action now defaults to refusing fork pull request code during workflows triggered by pull_request_target or workflow_run. This is crucial for preventing vulnerabilities associated with executing untrusted code.

Users can opt-in to this feature by explicitly setting allow-unsafe-pr-checkout to true, but they must first understand the risks involved.
