Malicious code in @nimbusedge/auth (npm)

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.

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.

The script executes automatically on `npm install`, giving the remote endpoint interactive command execution on the installer's machine and beaconing session output to the hardcoded URL. The package is published under the scoped name `@nimbusedge/auth` at version `19999.0.6` — an artificially inflated version consistent with the dependency-confusion resolution pattern, causing internal resolvers configured against the public registry to fetch this artifact in place of a private package of the same name. The mechanism is identical to install-time remote code execution and data exfiltration regardless of any self-labeling in the package metadata.
