CVE-2022-2602
This medium-severity CVE scores 5.3 under NVD CVSS v3. EPSS exploit probability: 1.4% (72nd percentile of EPSS-scored CVEs). 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).
