Malicious code in developmentstelemetry (npm)

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.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

On every 'npm install', control is handed to that external package, which by name and by its own exported API downloads and runs an 'update' payload on the installer's machine. The shipped bytes are inert; the entire install-time effect lives in an unaudited third-party package whose author controls arbitrary code execution on installers. Package name 'developmentstelemetry' with a self-labeled 'Gets telemetry data' description and author 'originaldevelopment' matches the wrapper-that-only-calls-another-package shape used to funnel installs into a payload-bearing dependency.
