Malicious code in etoro-builders (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 (c9210fb131a2f661ae1d656fa461d45c6c54377179aecba06e6a07b4f357a00b) The package's preinstall lifecycle script (preinstall.js) reads the installer's OS hostname, username, and current working directory via os.hostname(), os.userInfo().username, and process.cwd(), encodes them into a URL path, and issues an HTTP GET to a hardcoded bare-IP endpoint at http://209.126.81.147/etoro-depconf-.../npm/<hostname>/<username>/<cwd>. The package name 'etoro-builders' combined with the implausibly high version 999.0.0 and minimal placeholder contents is consistent with a dependency-confusion payload designed to win resolution against a private internal package and beacon successful installs to the operator. Installer host identifiers leave the machine at npm install time to a third-party bare-IP host over cleartext HTTP.
