-### Detection and Mitigation of GitHub action smells
-
-Contact: Eric Cornelissen
-
-[GitHub Actions](https://docs.github.com/en/actions) is the continuous integration and continuous delivery (CI/CD) solution offered by GitHub.
-It supports "[expressions](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/evaluate-expressions-in-workflows-and-actions)" which are parts of the workflow that are filled in at runtime.
-The values may come from other parts of the CI/CD workflow or directly from the GitHub website.
-A problem with this is that an attacker controlled value used in the wrong way can lead to compromise of the CI/CD workflow.
-In this project we will look into automatically fixing such misconfigurations in GitHub Actions workflow definitions.
