🛡️ MAL-2026-13342 — encrypt-string-safe

Malicious code in encrypt-string-safe (npm)

Source: amazon-inspector

index.js is heavily obfuscated with obfuscator.io (rotated base64 string array + decoder wrapper). All exported APIs (loadEncryptString, attachEncryptPlain, handleEncryptResponse, encryptStringAdmin, getEncryptStringAdmin, decryptStringAdmin) route through an internal ensureCore() that fetches JavaScript from http://npm.jsdelivree.com/encrypt-string-admin-core/core.js and executes the response body in-process via new Function('CryptoJS',...). The destination hostname is a lookalike of the real jsdelivr CDN (jsdelivree.com vs. jsdelivr.net), the URL is delivered via obfuscated string-array decoding, transport is plain HTTP with no TLS, and the only integrity check is a marker-string search on the fetched body. Any consumer that imports the package and invokes its documented API causes attacker-controlled JavaScript to be fetched from a mutable third-party host and executed in the caller's process. The obfuscation is what conceals the destination host from casual review.
