Findings 2
Import-time side effects
NPS-4A32F241ABC5
Top-level code executes immediately on import (module side effect), modifying the global window object. This behavior can be exploited in some supply chain attacks to alter environment assumptions of other modules, though here it appears benign.
Global scope pollution
NPS-1AC0F1383C09
The code unconditionally assigns Buffer, global, and process to the window object when a browser environment is detected. While common in polyfill shims, this mutates global state and could interfere with other libraries or mask native implementations. It does not directly exfiltrate data but modifies runtime environment.
Files reviewed
| File | Verdict | What the reviewer saw |
|---|---|---|
| dist/esm/index.js | medium | The module is a benign polyfill that assigns Node.js globals to window at import time, but it performs global scope pollution and import-time side effects that warrant caution. |
