Vulnerability
Malicious code in ect-472839-ctf (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (a67248cb7373817da18e0edf4a019e2e6c9ded239e93a2e477ac168f7f45eeaa) package.json declares a preinstall hook (`"preinstall": "node index.js"`) that auto-executes on `npm install`. index.js issues an HTTP GET to the hardcoded bare IP `10.107.121.85:8000` at path `/ping_472839_ctf`. The unique token in the URL path makes the request itself the exfiltrated signal — it confirms to the operator of that endpoint that the package executed inside the installer's environment, leaking the installer's source IP and the fact that code execution succeeded. The package advertises no functionality that would justify a phone-home, and the destination is a private-range IP rather than any documented service. This is the canonical dependency-confusion / CTF probe shape, and the same mechanism would deliver any payload an attacker placed in index.js.

For interim severity, fall back on KEV / EXPLOIT signals and the EPSS percentile (lower panel). Re-check this CVE after one cron tick — the score lands automatically when the source publishes.
FIRST.org publishes EPSS daily. Coverage isn't universal — pre-disclosure CVEs and reserved IDs don't carry an EPSS score until at least one exploitation signal lands. Score will appear within 24 hours of the next EPSS pull.
No exploitation, limited impact or prevalence
