 If a GitHub Actions job or workflow has no explicit permissions set, then the repository permissions are used. Repositories created under organizations inherit the organization permissions. The organizations or repositories created before February 2023 have the default permissions set to read-write. Often these permissions do not adhere to the principle of least privilege and can be reduced to read-only, leaving the `write` permission only to a specific types as `issues: write` or `pull-requests: write`.

 When the workflow runner cannot determine what secrets are needed to run the workflow, it will pass all the available secrets to the runner including organization and repository secrets.

 Only pass those secrets that are needed by the workflow. Avoid using expressions such as `toJSON(secrets)` or dynamically accessed secrets such as `secrets[format('GH_PAT_%s', matrix.env)]` since the workflow will need to receive all secrets to decide at runtime which one needs to be used.
