Explore global source statements, affected packages and advisory history for CVE-2026-69522. The catalog has a separate collection scope from Microsoft release records.

Collected exploitation and prediction evidence

Risk source coverage

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.

CVE-2026-69522

No KEV entry is attached to this observation; this is not evidence that exploitation is absent.

FIRST EPSS: 0.84 % · percentile 58.07 % · scored 10 Nov 2026.

Observed 10 Nov 2026 20:24:10 UTC · Complete immutable risk JSON

Dated risk observations

Risk history is separate from CNA/OSV content history. Daily score drift is retained but only an upward crossing of 10% triggers the prediction change event.

Immutable source observations

18 recorded revisions

Each citation identifies one complete source statement. Source modification dates and the time this installation observed them are distinct. Latest history includes records historically associated by source identifiers; a removed alias is not a current equivalence claim. Exact citations show that source record's own earlier observations. Failed reads and unchanged polls do not rewrite history.
