Malicious code in internallib_v875 (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details.

Any consumer that requires this package and calls the exported function triggers a fetch-and-execute of attacker-controlled shell content, giving whoever controls that IP:port an interactive shell on the host. The destination is unrelated to any legitimate publisher, the fetched bytes are executed without verification, and the package has no other functionality consistent with its name.
