Malicious code in web-main (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 (61680a5d53758bc9eb99b1cd2566e6e19139d09fee10a0096a5e72bb0953a5b2) package.json declares `preinstall: node index.js`, causing index.js to execute automatically on `npm install`. The script collects os.hostname(), os.userInfo() (username/uid/gid/shell), platform, arch, homedir, and the stdout of `whoami`, `id`, and `pwd` via child_process.exec, then POSTs the aggregated JSON to a hardcoded endpoint at https://smi54v4uvb9q7ve5t6fnyro16scj0co1.oastify.com/system-info (a Burp Collaborator out-of-band host). No legitimate functionality is present; the package's sole effect on install is host reconnaissance and exfiltration to an attacker-controlled OOB collector.
