This high-severity CVE scores 8.1 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 36% 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).
