What is MAL-2026-14534?
MAL-2026-14534 is a malicious package in commonjs-code-token, published on 26 Aug 2026.
Official description
On npm install, the package's postinstall hook runs index.js, which fetches JSON from https://access-token-delta.vercel.app and passes the returned
token field directly to eval(). Whoever controls that endpoint obtains arbitrary code execution on the installing machine, and the fetched content is mutable at any time. The package advertises itself with a README for an unrelated multithreaded cache library (node-cache-multithread) while the actual package identity is commonjs-code-token, a metadata/behavior mismatch consistent with a cover story. No legitimate functionality is shipped in the package.What should I do about MAL-2026-14534?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
