Summary by CodeRabbit

  • Documentation
    • Added a template configuration file for the security scanner with comprehensive inline comments. Includes examples for ignored vulnerabilities and package overrides. No active rules enabled; default behavior remains unchanged.
  • Chores
    • Introduced a baseline configuration file to standardize future scanner setup. Provides commented examples for actions (ignore, vulnerability/license ignore/override) and optional fields like effectiveUntil and reason. No impact on runtime behavior.

Poem

I nibble notes in TOML rows,
A burrow of comments, nothing goes.
No vulns ignored, just trails to see—
Example paths for you and me.
With whiskered grin and config cheer,
Our scanner’s ready—carrots near! 🥕

1-21: Add OSV-Scanner to CI
We didn’t find any existing OSV-Scanner integration in your workflows. To enforce this new config, please add a GitHub Actions workflow that runs the scanner on every push and pull request.

• Create .github/workflows/osv-scanner.yml with something like:

name: OSV Vulnerability Scan
on:
  push:
    branches: [ main ]
  pull_request:
jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: google/osv-scanner-action@v1
        with:
          config_file: osv-scanner.toml

• Ensure the path to your config is correct and commit the new workflow.

5-9: Tighten examples: document supported ID types and prefer RFC3339 date format

Minor clarity improvements to reduce future confusion for contributors.

Apply this diff to enrich the examples:

-# id = "CVE-YYYY-XXXX"
-# # ignoreUntil = 2025-12-31
-# reason = "why this is safe to ignore"
+# id = "CVE-YYYY-XXXX"         # also supports OSV-YYYY-NNNN and GHSA-xxxx IDs
+# # ignoreUntil = 2025-12-31T00:00:00Z
+# reason = "why this is safe to ignore"

11-13: Optional: include a second match example for Maven/Go to signal ecosystem-specific fields

A small addition can help users discover fields like group (Maven) or module path (Go).

Example (comment-only):

 # # Match fields (any subset): name, version, ecosystem, group
 # name = "axios"
 # ecosystem = "npm"
+# # Example (Maven):
+# # name = "log4j-core"
+# # group = "org.apache.logging.log4j"
+# # ecosystem = "Maven"

1-21: CI integration suggestion: add/confirm an automated OSV scan step

Now that a policy file is present, consider adding a CI job (e.g., GitHub Action) to run osv-scanner with this config and fail on new vulns while honoring policy exceptions.

If you want, I can draft a minimal GitHub Actions workflow (push/PR) using google/osv-scanner-action that points to this config.

1-3: Template-only config is safe and non-invasive

Adding a commented template that mirrors default behavior is a low-risk way to introduce OSV-Scanner policy. No behavior changes at runtime.


10-20: Revert to top-level action keys and YYYY-MM-DD expiry format

The upstream schema defines all action flags (ignore, vulnerability.ignore, license.ignore, license.override) as top-level keys within each [[PackageOverrides]] block—not under an [actions] table—and expiry fields use a simple YYYY-MM-DD string. The suggested actions.* prefix and RFC3339 timestamp aren’t supported.

• Keep the original example keys and date format:

[[PackageOverrides]]
name = "axios"
ecosystem = "npm"
# Actions (pick any):
ignore = true                  # ignore both vulns and license
vulnerability.ignore = true    # ignore only vulnerabilities
license.ignore = true          # ignore only license
license.override = ["MIT"]     # override license(s)
effectiveUntil = "2025-12-31"  # expiry date in YYYY-MM-DD
reason = "temporary exception"
