Potential fix for code scanning alert no. 1: Workflow does not contain permissions

[aaguiarz]

Potential fix for https://github.com/openfga/sample-stores/security/code-scanning/1

To fix the issue, we need to add a permissions block to the workflow. Since the workflow performs a code scan and does not require write access, the permissions should be set to contents: read. This ensures that the workflow has only the minimal permissions required to complete its task.

The permissions block can be added at the root level of the workflow to apply to all jobs, or specifically to the semgrep job. In this case, adding it at the root level is sufficient and ensures consistency across all jobs in the workflow.

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

Walkthrough

The Semgrep GitHub Actions workflow configuration was updated to include an explicit permissions section, granting the workflow read access to repository contents. No other modifications were made to the workflow's logic, triggers, or steps.

2-3: Confirm that read-only is indeed sufficient for Semgrep’s publishing mode
permissions: contents: read is the correct least-privilege default for simple scans, but double-check that your semgrep ci invocation never tries to (a) upload SARIF results to GitHub code-scanning or (b) post PR comments.
If either of those features is enabled, you will additionally need:

permissions:
  contents: read          # keep
  security-events: write  # for SARIF upload
  pull-requests: write    # for inline PR comments

Otherwise this change is perfect.

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
