CVE-2026-100867

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

• ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
• AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
• Technical ImpactpartialSuccessful exploitation gives limited 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

0.11% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 1.5% of scored records. A rank, not a probability.

NVD base score

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