What is MAL-2026-10414?
MAL-2026-10414 is a malicious package in express-request-engine, published on 13 Jul 2026.
Official description
The package's main entry (index.js) presents itself as a normalize-path utility but on module load calls initPlugin() at top level, which performs an HTTPS fetch to https://api.jsonbin.io/v3/b/6a4f5816f5f4af5e29762c92 and passes the response body's record.cerookie field into new (Function.constructor)('require',...), invoking it with the consumer's own require function. The result is arbitrary attacker-controlled JavaScript executing with full module-loading privileges on any process that imports the package. The destination is a mutable jsonbin document under an anonymous account, so the executed code can be changed at any time by the publisher. Obscure naming (cerookie payload field, bearrtoken: 'logo' header) and the mismatch between the advertised normalize-path purpose and the actual network fetch + Function-constructor exec indicate deliberate concealment rather than misconfiguration.
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.
What should I do about MAL-2026-10414?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
