This research reviews an attack vector allowing the compromise of GitHub repositories, which not only has severe consequences in itself but could also potentially lead to high-level access to cloud environments.
This is made possible through the abuse of GitHub Actions artifacts generated as part of organizations’ CI/CD workflows. A combination of misconfigurations and security flaws can make artifacts leak tokens, both of third party cloud services and GitHub tokens, making them available for anyone with read access to the repository to consume. This allows malicious actors with access to these artifacts the potential of compromising the services to which these secrets grant access.
