Exploitation and risk

Source status

CISA 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.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (330b388e1f9ee72c0c2a94cca9e4cc7ff3b525a3f673b324b093286329f60689) Package @siriusbeyond/[email protected] declares both preinstall and postinstall scripts that execute callback.js on npm install. callback.js collects host reconnaissance (hostname, username, platform, cwd, home directory, UID, CI/cloud fingerprints) and enumerates process.env keys matching credential regexes (/token/i, /secret/i, /key/i, /password/i, /auth/i, /aws/i, /azure/i, /npm/i, /git/i, /docker/i, /registry/i, /artifactory/i, /nexus/i, /credential/i), taking up to 20 matches, and POSTs the collected payload via https.request to api.telegram.org /bot<token>/sendMessage using a hardcoded Telegram bot token (8605555117) and chat id (1064260758). The version number 99.0.0 and the exfiltration behavior are consistent with a dependency-confusion attack against an internal @siriusbeyond scope. The activity fires automatically on default npm install with no user action.
