CVE-2026-40034

Exploitation

Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.

SSVC decision

• ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
• AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
• Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.65% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 50.9% of scored records. A rank, not a probability.

NVD base score

8.5 (CVSS v4.0), scored by the NVD independently of the CNA.
