OpenSSF ScorecardJul 20, 2026

OpenSSF Scorecard is an automated audit of the source repository's security practices, run by the Open Source Security Foundation. Each check scores 0-10; hover a check for what it means. Data via deps.dev.
  • Binary-ArtifactsNo compiled binaries are committed to the repository — binaries can't be reviewed and may hide malicious code.Result: no binaries found in the repo10
  • Dangerous-WorkflowGitHub Actions workflows avoid dangerous patterns such as untrusted code checkout or script injection.Result: no dangerous workflow patterns detected10
  • MaintainedThe project shows recent activity: commits or issue triage within the last 90 days.Result: 9 commit(s) and 1 issue activity found in the last 90 days -- score normalized to 88
  • Code-ReviewChanges are reviewed by another maintainer before landing on the main branch.Result: Found 10/27 approved changesets -- score normalized to 33
  • Security-PolicyA SECURITY.md explains how to report vulnerabilities privately.Result: security policy file detected10
  • Pinned-DependenciesBuild dependencies are pinned to exact versions or hashes, preventing silent supply-chain swaps.Result: dependency not pinned by hash detected -- score normalized to 11
  • Token-PermissionsCI workflow tokens follow least privilege — read-only unless a job needs more.Result: detected GitHub workflow tokens with excessive permissions0
  • CII-Best-PracticesThe project holds an OpenSSF Best Practices badge, a self-certification of security practices.Result: no effort to earn an OpenSSF best practices badge detected0
  • FuzzingThe project is fuzz-tested (e.g. OSS-Fuzz), which finds crashes and memory bugs automatically.Result: project is not fuzzed0
  • LicenseThe project publishes a license file.Result: license file detected9
  • Branch-ProtectionThe default branch is protected: force pushes are blocked and changes require review before merging.Result: branch protection is not maximal on development and all release branches6
  • SASTStatic analysis (e.g. CodeQL) runs on pull requests to catch bugs before merge.Result: SAST tool is not run on all commits -- score normalized to 00
