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 (c1ac938360c682e2489d11de9278697e7e2e85d73c612d2ab60ed28553bb5573) The package's preinstall script (scripts.preinstall = 'node index.js') runs automatically on npm install and collects os.userInfo().username and os.hostname(), then issues a dns.lookup against a subdomain of 31ee29fe-db68-4fd3-86a2-2b707b9e95f0.dnshook.site with the username and hostname embedded in the queried label. This is a DNS-based exfiltration beacon: installing the package transmits installer host identifiers to a non-first-party canary domain over DNS resolution at install time. The version number 99.99.99 and package name shape are consistent with a dependency-confusion lure targeting an internal package name.
