CVSS severity
Critical (9.8/10)CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Sourced from NVD — reflects how severe this vulnerability is if exploited, not whether it has been. Every advisory on this page is already a CISA-confirmed active exploitation case regardless of its CVSS score.
EPSS — exploit probability
Low0.33%
estimated chance of real-world exploitation in the next 30 days — higher than 26.3% of every CVE FIRST.org scores
Refreshed 9/22/2026 — via FIRST.org's EPSS model, not CVSS — this measures likelihood of exploitation, not how severe it would be.
Required action
