GITHUB_TOKEN permissions used by this action #100

Closed step-security-bot closed 2 years ago

step-security-bot commented 2 years ago

At https://github.com/step-security/secure-workflows we are building a knowledge-base (KB) of GITHUB_TOKEN permissions needed by different GitHub Actions. When developers try to set minimum token permissions for their workflows, they can use this knowledge-base instead of trying to research permissions needed by each GitHub Action they use.

Below you can see the KB of your GITHUB Action.

name: 'Setup Haskell' # haskell/actions/setup
# GITHUB_TOKEN not used

If you think this information is not accurate, or if in the future your GitHub Action starts using a different set of permissions, please create an issue at https://github.com/step-security/secure-workflows/issues to let us know.

This issue is automatically created by our analysis bot, feel free to close after reading :)

GitHub asks users to define workflow permissions, see https://github.blog/changelog/2021-04-20-github-actions-control-permissions-for-github_token/ and https://docs.github.com/en/actions/security-guides/automatic-token-authentication#modifying-the-permissions-for-the-github_token for securing GitHub workflows against supply-chain attacks.

Setting minimum token permissions is also checked for by Open Source Security Foundation (OpenSSF) Scorecards. Scorecards recommend using https://github.com/step-security/secure-workflows so developers can fix this issue in an easier manner.

Yep; we don't use it and never will (unless it would somehow be required for intelligent caching).

Would be cool to be able to specify the permissions of the action token inside the action.yml file so that I would have to opt-in rather than making everyone else opt-out. But ah well
