Potential fix for code scanning alert: Workflow does not contain permissions

[adelg003]

Potential fix for https://github.com/adelg003/fletcher/security/code-scanning/15

To fix the problem, add a permissions block to the workflow file .github/workflows/*.yaml. The block should be placed at the top level of the workflow, so it applies to all jobs unless overridden. Since none of the jobs require write access to repository contents or other resources, the minimal required permission is contents: read. This change should be made immediately after the name: and before the on: block (typically after line 1 or 2). No additional imports or definitions are needed.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.

Summary by CodeRabbit

• Chores
  • Hardened CI by setting the workflow token to read-only for repository contents across all pipelines (e.g., Docker, Markdown checks, Python, Rust, Trivy).
  • No changes to triggers, jobs, or steps; build, test, and scanning behavior remains the same.
  • Aligns workflows with least-privilege best practices without impacting end-user functionality. Improves security posture.

Walkthrough

Added a top-level permissions block (contents: read) to five GitHub Actions workflows. No changes to triggers, jobs, or steps.

Poem

I nudge the YAML, light and neat,
A read-only token, small and sweet.
Five workflows hop in tidy line,
Least we grant, and all is fine.
Thump of paws—secure delight! 🐇✨

Learning: adelg003 prefers to defer infrastructure optimizations (like external report hosting) until there's a clear need, choosing pragmatic solutions that provide immediate value over premature optimization that adds complexity.

🔇 Additional comments (10)

.github/workflows/docker.yaml (2)

2-3: LGTM: Least-privilege top-level permissions correctly added and placed

Placement (immediately after name:) and scope (contents: read) align with the alert remediation and apply to all jobs by default.

---

2-3: No additional permissions required for Docker workflow
Both docker-build and docker-healthcheck jobs only checkout code and run local build/healthcheck commands—they don’t push images or upload SARIF results. Your top-level

permissions:
  contents: read

is sufficient.

.github/workflows/trivy.yaml (2)

2-3: LGTM: Correctly scoped and positioned permissions block

contents: read at the workflow level is appropriate given no write operations in the jobs.

---

2-3: Heads-up: Trivy SARIF uploads would need security-events: write

If you later add “upload-sarif” for Trivy results, define job-level permissions: security-events: write. Current workflows don’t show that, so this minimal scope is fine.

Use the repo-wide scan to confirm there’s no SARIF upload configured (same script as in the Docker workflow comment).

.github/workflows/python.yaml (2)

2-3: LGTM: Minimal permission set matches workflow needs

contents: read suffices for checkout and read-only operations (pyright, ruff, pip-audit).

---

2-3: Double-check tool behaviors that may require extra scopes

• actions/cache (if added later) may need actions: write to create caches.
• Uploading SARIF from pip-audit would need security-events: write.
  If added, override at the job-level only.

Run the same workflow scan script to ensure none of these are present today.

.github/workflows/rust.yaml (2)

2-3: LGTM: Least-privilege workflow token now enforced

contents: read is appropriate; jobs (clippy, fmt, tests, deny) don’t write to repo or services.

---

2-3: Confirm no image pushes or OIDC auth present

If you later push to registries, you’ll need packages: write; for cloud OIDC, id-token: write. Add as job-level overrides only when needed.

The provided scan script will flag docker/build-push-action, login actions, or OIDC auth usage if present.

.github/workflows/markdown.yaml (2)

2-3: LGTM: Properly added top-level permissions with minimal scope

Placement and scope meet the code scanning recommendation and keep the token read-only by default.

---

2-3: Sanity-check that no write operations exist in this workflow

Current steps only lint docs. If future steps write to the repo (e.g., autofixing), add job-level contents: write only there.

Use the same scan script to keep an eye on additions that may require broader permissions.
