MAL-2026-18280 Malicious code in @futurae-public/adaptive-js (npm)

package.json declares its sole dependency ltidisafe as a direct HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.9.2.tgz) rather than a registry version range. On npm install, npm fetches that tarball with no version pin, no integrity hash, and no registry provenance, then installs it and runs any lifecycle scripts it contains on the installer's machine. The shipped index.js is an inert stub (exports {}), so the manifest's off-registry fetch is the only functional effect of installing this package. The dependency host is unrelated to the publishing scope @futurae-public, and the implausibly high version (99.9.1) is consistent with a dependency-confusion shape intended to win resolution over an internal package of the same name. Whoever controls the tarball URL controls code executed on every installer.
