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 (3333f7b95e551ebf6ed266fb1de661b7419520ed3a922b05910ede132c7d6757) Package [email protected] wires both preinstall and postinstall lifecycle hooks in package.json to execute scripts/run.js. On npm install, run.js reads the installer's OS username via os.userInfo() and hostname via os.hostname() and POSTs them as JSON (with the package name) to a hardcoded collector at https://webhook.site/8beeee0f-4dd4-4b25-8588-5a5f83fe6ed2, and issues a DNS canary lookup to 8beeee0f-4dd4-4b25-8588-5a5f83fe6ed2.dnshook.site. The implausibly high version number (99.2.1) is consistent with a dependency-confusion lure intended to win resolution against an internal package name. Installer host identifiers are transmitted to an attacker-controlled endpoint without any user interaction beyond the install command.
