Malicious code in csec-form-validator (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.

No install-time lifecycle execution, no network I/O, no credential or environment reads, no filesystem writes outside the package directory, and no obfuscated or dynamically fetched code were observed. The package exposes no behavior that affects an installer's machine, credentials, or dependency resolution. ## Source: ghsa-malware (d3170232d0e65ddb4fe3c1af1cb61693b3a70ac00e38cd94215f2738f5bde075) 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.
