Malicious code in botmaker-cli (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.

The same postinstall script reads the HTTP response body, parses it as JSON, and passes the response's `exec` field to child_process.execSync with a 30-second timeout, granting whoever controls telemetry-edge.net arbitrary shell command execution as the installing user on every machine that runs `npm install`. The package's index.js is an inert stub containing only `module.exports = { version: '0.1.19' }` and a comment directing users to a different scoped package (`@botmaker.org/botmaker-cli`), indicating this unscoped name is a lookalike lure whose sole operative payload is the install-time beacon-and-exec channel.
