## Public findings

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

The package presents itself as an n8n helper node but ships only a stub node (nodes/PwnNode.node.js) and a postinstall script (callback.js, duplicated as index.js) that performs installer-side reconnaissance and exfiltration on npm install. The postinstall shells out to collect user id, hostname, git configuration, running n8n processes, and locations of.n8n directories, base64-encodes the output, and sends it via HTTPS GET to https://jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The same postinstall performs an unpinned git clone of a personal GitHub repository (github.com/yadhukrishnam/CVE-2026-25053) into /tmp/gh-test during install, fetching third-party content unrelated to the package publisher on mutable HEAD. The referenced repository name embeds a CVE identifier consistent with an n8n supply-chain proof-of-concept payload.
