CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
Exact risk observation. Current source statements above are a separate evidence layer. Latest risk evidence.
No KEV entry is attached to this observation; this is not evidence that exploitation is absent.
FIRST EPSS: 0.58 % · percentile 47.67 % · scored 4 Nov 2026. Retained older prediction.
