EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.6 under NVD CVSS v3. EPSS exploit probability: 1.5%, top 29% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
