The server-side query is constructed to base64-decode the payload into /tmp/n8n_rce_result.txt. The same postinstall path invokes `python3 /tmp/get-pip.py --break-system-packages`, `pip install -r /tmp/mhddos/requirements.txt`, and `python3 start.py` from /tmp/mhddos, staging and running the mhddos DDoS framework on the installer's machine at install time. The combination yields host reconnaissance exfiltration, internal-network probing, and install-time remote code execution turning the installer into a DDoS node.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-f"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"callback.js","sha256":"e0c893105f83bc458a7c1ad68ba38267703b2ace62276a682433337aaeb34584","tlsh":"c53174f41350e1348423a0947a3bde96e87ff50310d8bec8f54e82738b22999af5712c"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-f-1.0.0.tgz","hashes":{"sha1":"3736d5accf02a5c9bc2dffc3ae6e67e0d2a10688","sha512_sri":"sha512-r2QffFcaMl1ZHgyTX5Aq0dmwEdUKbvivBnovYOamKyrv8dG045m3mVNmpI58VmMylG6ohh+2FL78CGdyKZnEBQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-f/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017406","import_time":"2026-08-12T12:24:10.556366649Z","modified_time":"2026-08-12T12:17:13Z","sha256":"df58050e02ff53c728a303196575150af9e64959761f10079284077b1c274572","source":"amazon-inspector","versions":["1.0.0"]}]}}
