Unspecified workflows level permissions

Metadata

ID: github-actions/permissions

Language: YAML

Severity: Warning

Category: Security

Description

Default permissions for the GITHUB_TOKEN are expected to be restricted (contents:read, metadata:read, and packages:read).

Your repository may require a different setup, so consider defining permissions for each job following the least privilege principle to restrict the impact of a possible compromise.

You can find the list of all possible permissions in Workflow syntax for GitHub Actions - GitHub Docs. They can be defined at the job or the workflow level.
