Scorecard

Scorecard 7.2/10

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

Check	Score	Reason
Code-Review	10	all changesets reviewed
Maintained	10	30 commit(s) and 7 issue activity found in the last 90 days -- score normalized to 10
CII-Best-Practices	0	no effort to earn an OpenSSF best practices badge detected
Security-Policy	10	security policy file detected
Dangerous-Workflow	10	no dangerous workflow patterns detected
License	10	license file detected
Token-Permissions	0	detected GitHub workflow tokens with excessive permissions
Binary-Artifacts	10	no binaries found in the repo
Branch-Protection	8	branch protection is not maximal on development and all release branches
Signed-Releases	-1	no releases found
Fuzzing	0	project is not fuzzed
Pinned-Dependencies	1	dependency not pinned by hash detected -- score normalized to 1
Packaging	10	packaging workflow detected
SAST	9	SAST tool detected but not run on all commits

OpenSSF Badge

OpenSSF none

Badge indicates adherence to open-source best practices.

CVE Patch History

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.
