## Public findings

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

@years20/n8n-nodes-utils-helper-j 1.0.0 runs a postinstall script (index.js/callback.js) that executes \`id\` and \`hostname\` on the installer host, base64-encodes the output, and sends it over HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The same script writes attacker-controlled content into /tmp/n8n\_rce\_result.txt and /tmp/filter\_pwned.txt, creates /tmp/src-repo, and configures a git \`filter.evil.smudge\` filter that shells out on checkout, staging follow-on command execution. The package presents itself as an n8n community node (nodes/PwnNode.node.js) but ships no legitimate node functionality; the recon/RCE-staging payload is the entire install-time behavior and fires automatically on \`npm install\`.
