MAL-2026-6088 Malicious code in vite-common-utils (npm)

The package presents itself as a Vite utility library but its only export, loadFilbetScriptSilently, creates a <script> element whose src is hardcoded to https://cdn.jsdelivr.net/gh/gongben2024/network-security@main/src/filbet.js and appends it to document.documentElement, causing the consuming application to fetch and execute whatever JavaScript that URL currently serves. The URL is unpinned (mutable @main branch), is hosted under a personal GitHub user account unrelated to the package publisher, and has no integrity/SRI check. The shipped dist/index.js is the only file in the package and is heavily mangled with obfuscator.io (string-array decoder, hex identifiers, rotation loop), and package.json's devDependencies include gulp-javascript-obfuscator — confirming the obfuscation is intentional and hides the injector. The export name suffixed 'Silently', the cover-story package name, the obfuscation, and the off-publisher mutable code source jointly indicate a remote-code-execution dropper aimed at the downstream web application's origin and its users.

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.
