Malicious code in @airbnb-extended/typescript-config (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. Do not edit below this line.=-_ ## Source: amazon-inspector (8424e4bf8731b950511535a2cb9b41b0bedba02092a73ea304b6730f04aa95fe) package.json for @airbnb-extended/[email protected] declares a dependency `ltidisafe` sourced from a bare HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.8.tgz) instead of a registry version range. On `npm install`, npm fetches and installs whatever bytes that URL returns, executing any lifecycle scripts inside the fetched tarball. The source is unpinned by integrity hash, is not the npm registry, and is unrelated to any Airbnb-published infrastructure. The scope/name also mimics the well-known `@airbnb/typescript-config` package, and the version `99.9.1` is implausibly high — a dependency-confusion / lure shape designed to win resolution against a legitimate internal or public package. The tarball URL is mutable by whoever controls the storage bucket, so the delivered payload can change at any time. ## Source: ghsa-malware (fb568c40ae85c1c7f780d9c27d2e9f096bb87e913fbbb6324a3ca50035dc3175) 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.
