Malicious code in messenger-style (npm)
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 (48e89235ade6dcbf682edae5afb7d789c6a834b2ebe032fac72c796734837d10) The package's preinstall hook runs `node index.js`, which collects host identifiers (`os.hostname()`, `os.userInfo().username`, home directory, DNS servers) and reads `/etc/passwd` and `/etc/hosts` from the installer's machine, then POSTs the collected data over HTTPS to the hardcoded host `pkdzrreksftymvx4d0o5olnxiooic80x.oastify.com` (a Burp Collaborator out-of-band interaction domain). The package name suggests a messaging utility, but no such functionality is present — the sole behavior on `npm install` is host reconnaissance and exfiltration to an attacker-controlled OAST endpoint.
