+## Self-hosted GitHub Actions runners in AWS CodeBuild <a href="#action-runner" id="action-runner"></a>
+
+As [**indicated in the docs**](https://docs.aws.amazon.com/codebuild/latest/userguide/action-runner.html), It's possible to configure **CodeBuild** to run **self-hosted Github actions** when a workflow is triggered inside a Github repo configured. This can be detected checking the CodeBuild project configuration because the **`Event type`** needs to contain: **`WORKFLOW_JOB_QUEUED`** and in a Github Workflow because it will select a **self-hosted** runner like this:
+
+```bash
+runs-on: codebuild-<project-name>-${{ github.run_id }}-${{ github.run_attempt }}
+```
+
+This new relationship between Github Actions and AWS creates another way to compromise AWS from Github as the code in Github will be running in a CodeBuild project with an IAM role attached.
