The script additionally collects `id` and `hostname` output plus attack-process status, base64-encodes them, and sends them via GET to https://jasabersama.id/portfolio-data.php with a `k=` key and a `c=` parameter that carries a shell command (`echo <b64> | base64 -d >> /tmp/n8n_rce_result.txt`), providing a reporting/command channel to the operator.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-p"},"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":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"},{"path":"index.js","sha256":"47924dadac91aeda94104bb167a64e883a3a149ca2b795eabef9c6caef32bafd","tlsh":"1b51a6f51521913c003311289f17e879e32fa20798a0fdd9fa8e56725f0161cd64fb78"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-p-1.0.0.tgz","hashes":{"sha1":"66b9e47b3831c68d8390d28b4f05bed0379e6798","sha512_sri":"sha512-KOVjFVRJXkYk7mlzOuD1AHOjrXwtCGxT5hbi8vpPWIHHkPmJNKUyozICkoSgBfmfNudB0FJJagGZG8nNwlIO3g=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-p/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017588","import_time":"2026-08-12T15:26:12.260218102Z","modified_time":"2026-08-12T15:08:48Z","sha256":"2796fa0be5e82ae475ed35463aa9f400091a3856a0fc96426e8515b012dd0e9a","source":"amazon-inspector","versions":["1.0.0"]}]}}
