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 (76315a0ce965c3a1f5b6342caa9d9ce8db4b341b641b2dbb696ebd52bd6149ec) On require/import, index.js issues an HTTPS GET to a hardcoded interactsh OAST subdomain (dapnhid534ch06s9vpm0mbg1httu5gytc.oast.fun) with the installer's os.platform() and os.hostname() as query parameters. The package ships no other functionality; its main module exists solely to fire this out-of-band beacon on load. oast.fun is a public out-of-band interaction collector used to receive callbacks from targets, and the hardcoded subdomain is bound to a specific listener controlled by whoever published the package. This is the canonical dependency-confusion / namesquat probe pattern, in which a package is published to catch internal-name mis-resolutions and report back the host that installed it.
