Ghostwire Analysis — What This Means Practically

Exploitation Probability (EPSS): Low — 0.16% (37th percentile)

Low exploitation probability based on current threat landscape data. Standard patching timeline is appropriate.

High CVSS score indicates significant risk — exploitation could lead to substantial data exposure or system compromise.
1 proof-of-concept exploit available on GitHub. Public exploit code lowers the barrier for both researchers and attackers.

This analysis is generated by Ghostwire from NVD, CISA KEV, EPSS, and open-source intelligence data. Verify findings through primary sources before acting.
