Malicious code in sorrawit-dev-helper (npm)
Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (c64040dcfbbdb6ce434caf3cd5bd2baa518cc00970281a69f5309d57a4621233) package.json declares a postinstall lifecycle script that runs automatically on `npm install`. The script reads /tmp/flag.txt from the installer's machine and sends its URL-encoded contents as a query parameter to a hardcoded ngrok tunnel at https://ca37-49-237-83-218.ngrok-free.app/. The destination is an ephemeral tunnel host unrelated to any legitimate publisher, and the read+exfil fires without user interaction. The behavior matches install-time credential/file exfiltration with a concrete installer-side data source and a concrete attacker-controlled destination.
