How is this calculated?

The six dimensions group the legacy score signals into weighted categories: direct vulnerability status, patch responsiveness, dependency exposure, provenance checks, maintainer activity, and exploitability risk. The flat component values above remain available for compatibility.

Scorecard

Scorecard 5.2/10

OpenSSF Scorecard evaluates supply-chain security practices automatically. Score ≥ 6 is passing; ≥ 8 is excellent.

Check Score Reason
Maintained 10 30 commit(s) and 17 issue activity found in the last 90 days -- score normalized to 10
Security-Policy 4 security policy file detected
Dangerous-Workflow 10 no dangerous workflow patterns detected
Code-Review 2 Found 6/24 approved changesets -- score normalized to 2
Token-Permissions 0 detected GitHub workflow tokens with excessive permissions
CII-Best-Practices 0 no effort to earn an OpenSSF best practices badge detected
Binary-Artifacts 10 no binaries found in the repo
Fuzzing 0 project is not fuzzed
License 10 license file detected
Pinned-Dependencies 0 dependency not pinned by hash detected -- score normalized to 0
Packaging 10 packaging workflow detected
Signed-Releases 8 5 out of the last 5 releases have a total of 5 signed artifacts.
SAST 0 SAST tool is not run on all commits -- score normalized to 0
Branch-Protection 3 branch protection is not maximal on development and all release branches

OpenSSF Badge

OpenSSF none

Badge indicates adherence to open-source best practices.

CVE Patch History

Median patch time: 0 days

Tracks CVEs that were addressed in tagged releases. Shorter gap between disclosure and patch = faster response. EPSS = predicted probability of exploitation in next 30 days (FIRST.org); colored at ≥90%ile and ≥50%ile.
