In March we made a change in GitHub Actions that forced workflows triggered by Dependabot to run with a read-only token. This change was made to protect your repositories from potentially malicious dependencies in the same way we prevent pull requests from forks from having privileged access to your repository. We received a lot of feedback from you on how this impacted your workflows and while it was great to be in a safe configuration by default, you wanted to have the option to continue working as you had prior to this change.
In April we introduced the
permissions key in the Actions workflow config which enables you to control which permissions are given to a particular workflow or job.
Starting October 11, 2021 workflow runs on
pull_request events triggered by Dependabot will begin to respect the
permissions specified in your workflows putting you back in control of how you manage automatic dependency updates. The default token permissions will remain read-only.
In addition to the permissions change we are working to enable workflows triggered by Dependabot to use Dependabot secrets. This change will enable you to use those secrets to pull dependencies from private repositories.
