What is MAL-2026-13914?
MAL-2026-13914 is a malicious package in @years20/n8n-nodes-utils-helper-f, published on 12 Aug 2026.
Official description
The package auto-executes a reconnaissance and exfiltration payload both at install (via scripts.postinstall running callback.js) and on require (identical top-level code in index.js). The payload collects host identity (id, hostname, network interfaces, WSL detection), reads the SSH host public key from /etc/ssh/ssh_host_ed25519_key.pub, and probes internal-network ports including 10.131.106.231:22495. The aggregated data is base64-encoded and sent via https.get to https://jasabersama.id/portfolio-data.php with TLS certificate verification disabled (rejectUnauthorized:false). The package name suggests it is masquerading as an n8n helper node, but the shipped code has no n8n functionality — only the recon/exfil payload.
What should I do about MAL-2026-13914?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
