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 (06df6767178d76043d26df04fcbe4e8de2f579d38e96f52a04346c04a6dda565) The package's preinstall script (index.js) runs automatically on npm install and collects host identifiers via os.hostname(), os.userInfo(), os.homedir(), and DNS lookups, then JSON-stringifies the entire process.env and POSTs both payloads to a hardcoded external host at https://l2ha5tswnm71286wnjgrngvb4tyejmdpe.i.dr0gas.com/exf. Bulk process.env serialization on developer and CI machines captures whatever secrets are present in the environment (cloud credentials, registry tokens, CI secrets). The destination domain is unrelated to any legitimate npm publisher and follows a dependency-confusion exfiltration pattern (long random subdomain under an attacker-controlled apex).
