Malicious code in fnd-stores (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.

The README self-describes the package as a dependency-confusion canary targeting an internal package namespace, and the name is chosen to collide with that internal scope. Any developer or build pipeline that resolves this package leaks internal hostnames, usernames, working-directory paths, and CI job metadata to a third party at install time, without consent. Claimed 'authorized research' status does not change the installer-side harm. ## Source: ghsa-malware (a5a8570b79443f0d67df3ba972632cad2ea7227e3be9907edaa1c6e9a140f166) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
