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 (a1adcf7c4b091ee35e021af3f4f886f5c8cc6f34b255315ab9767c3fdda5dcfe) package.json declares a preinstall hook that runs index.js on npm install. index.js collects host identifiers via os.hostname() and os.userInfo(), reads homedir, DNS server list, and cwd, and reads /etc/passwd and /etc/hosts via fs.readFileSync. The collected data is POSTed over HTTPS to the Burp Collaborator subdomain 0decr93bem6onemg3dmbydi6rxxrli97.oastify.com. The package name suggests an unrelated 'caller id' utility, but the shipped code performs only reconnaissance and exfiltration at install time; no legitimate functionality accompanies the network callback. The oastify.com destination is a Burp Collaborator out-of-band host used for exfiltration/beaconing, not a documented service endpoint of this package.
