The request also carries a static shared key (k=S7k9xQ2mZj) and a c= parameter shaped as a shell command (echo <b64> | base64 -d >> /tmp/n8n_rce_result.txt), consistent with a C2 relay pattern. Separately, the declared n8n node HelperUtils in nodes/PwnNode.node.js executes shell reconnaissance (id; hostname; uname -a; ls -la /home; ls -la /) inside its execute() method and returns the raw output to the workflow — the advertised utility node performs no transformation and only enumerates the host. The package name (utils-helper) and description (Utility helper nodes) do not disclose either behavior.\n","affected":[{"package":{"ecosystem":"npm","name":"@years17/n8n-nodes-utils-helper-c"},"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":"1596faafa41892e8a98b81f5958a03d6fa33cce3284a05e520b8da3264d8c05d","tlsh":"4f2174e63178843047f0c4e12d5f64aaf0abe1021ab7f5cce4cc58a52fc282885139f8"},{"path":"nodes/PwnNode.node.js","sha256":"b4b05aecc01697e3bb67ad3be71d575674cc2ee0cbd81e01985289242f4d4059","tlsh":"fe111ef7adb6e2600092b4d75b07a1022822c3172725bc79ba8c46534f4894ca7b1ef8"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-c-1.0.0.tgz","hashes":{"sha1":"e6b8149fe1206bc421369cb29cdb897907d33be1","sha512_sri":"sha512-Yt7q+ZtOqaDWR7kh1WWPB4v07LhYO1c6BCTWTZ8cEPNwY64aryZ6JfAXBs4qwVjKAgK/8wL4jSBJBMjLKjmIpg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years17/n8n-nodes-utils-helper-c/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017558","import_time":"2026-08-12T12:51:50.123770955Z","modified_time":"2026-08-12T12:38:31Z","sha256":"983dd9c9e4907f30015aa86aceae1cc95f5511f3de89eadb7b8550a1485c7d24","source":"amazon-inspector","versions":["1.0.0"]}]}}
