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.
Supply Chain Risk
Risk 14.0/100Scorecard
Scorecard 3.8/10OpenSSF Scorecard evaluates supply-chain security practices automatically. Score ≥ 6 is passing; ≥ 8 is excellent.
