CVE-2022-44149
Score elevated to 8.9 because EPSS predicts 64% probability of exploitation within the next 30 days (top 0.8% of all CVEs). NVD baseline CVSS 8.8 retained for reference. Confidence: see factors.
- High exploitation likelihood — EPSS 64%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
