does github actions run as root

Does GitHub Actions run as root by default?

Yes, GitHub Actions runs as root by default. This is because GitHub Actions runs on a virtual environment that is provisioned with root privileges. This allows GitHub Actions to have access to all the resources that are necessary to run your workflows.

Can GitHub Actions be configured to run as a non-root user?

Yes, GitHub Actions can be configured to run as a non-root user. To do this, you can use the user keyword in your workflow file. For example:

<code>jobs:
  my-job:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: whoami</code>

This workflow will run as the ubuntu user.

What are the security implications of GitHub Actions running as root?

There are a number of security implications to consider when running GitHub Actions as root. These include:

• Increased risk of privilege escalation: If an attacker is able to gain access to your GitHub Actions runner, they could use it to escalate their privileges to root. This could give them access to all of the resources on your GitHub repository, including your code and secrets.
• Increased attack surface: Running GitHub Actions as root increases the attack surface of your application. This is because there are more potential entry points for attackers to exploit.
• Increased risk of data breaches: If an attacker is able to compromise your GitHub Actions runner, they could potentially access your data. This could include sensitive information such as customer data, financial information, or intellectual property.

It is important to weigh the risks and benefits of running GitHub Actions as root before making a decision. If you are concerned about the security implications, you should consider configuring GitHub Actions to run as a non-root user.
