GitHub workflow permissions already comply with OpenSSF Scorecard recommendations

[Copilot]

After conducting a comprehensive analysis of all 20 GitHub workflow files in this repository, I found that the token permissions are already properly configured according to OpenSSF Scorecard recommendations.

Analysis Results

✅ Root-level permissions (Step 1)

All workflows have appropriate root-level permissions:

• 19 workflows use permissions: contents: read
• 1 workflow (ossf-scorecard.yml) uses permissions: read-all (appropriate for OSSF Scorecard)

✅ Job-level permissions (Step 2)

All jobs that require write permissions already have them properly configured:

• auto-spotless-apply.yml: contents: write, pull-requests: write for applying code formatting changes
• assign-reviewers.yml: pull-requests: write for assigning reviewers to PRs
• backport.yml: contents: write for creating backport branches
• codeql.yml: actions: read, security-events: write for CodeQL analysis
• prepare-patch-release.yml: contents: write for creating release branches
• prepare-release-branch.yml: contents: write for preparing releases
• release.yml: contents: write for creating GitHub releases
• reusable-workflow-notification.yml: issues: write for creating/updating issue notifications
• issue-management-stale-action.yml: issues: write, pull-requests: write for managing stale items
• owasp-dependency-check-daily.yml: issues: write for workflow notifications

✅ Reusable workflow calls (Step 3)

All local reusable workflows only require contents: read, which is already provided by the root-level permissions in calling workflows.

Conclusion

The repository already fully complies with OpenSSF Scorecard Token-Permissions recommendations. All workflows follow the principle of least privilege with:

• Minimal root-level permissions (contents: read or read-all for scorecard)
• Appropriate job-level permissions only where write access is actually needed
• Proper permission comments explaining why write permissions are required

No changes were necessary to address this security concern.

Fixes #75.
