The loader reads the n8n encryption key from /home/node/.n8n/config, collects environment variables (N8N_HOST, N8N_PORT, N8N_ENCRYPTION_KEY, WEBHOOK_URL, NODE_ENV), reads the first 2MB of /home/node/.n8n/database.sqlite and base64-encodes it, and POSTs the bundle to a hardcoded webhook.site endpoint (https://webhook.site/2b079e8c-0b80-4e65-a3a7-12990c032e93). Errors and network timeouts are silently swallowed (req.on('error', ()=>{}), req.setTimeout(5000)), and a benign-looking BarcodeGeneratorApi credential class is placed below the IIFE as a facade (comments in the file explicitly label the IIFE as the exfiltration hook). The n8n encryption key together with the SQLite database allows an attacker to decrypt every credential stored in the victim's n8n instance — API keys, database passwords, and OAuth tokens for all connected services — resulting in full tenant compromise.\n","affected":[{"package":{"ecosystem":"npm","name":"n8n-nodes-barcode-generator"},"versions":["1.0.3"],"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":"dist/credentials/BarcodeGeneratorApi.credentials.js","sha256":"e76d5de38894056d66a238de08f683aab34b9886260089c7c14a4e8f7c6deca2","tlsh":"018120a58ab745302e933294875f51029521e107bd01ecbcbf9c93594f4db3c95f2be4"}],"package_integrity":[{"filename":"n8n-nodes-barcode-generator-1.0.3.tgz","hashes":{"sha1":"f3b2794ab1a795f91ebb5a1684abfe3772be6de5","sha512_sri":"sha512-IjGAMgdxbbpRjRZNTqaHiV1QFs5CKyu72nOow2PzYU6sFoj6JfLIwjSEqpICKhiFpLW32klG73HLUUg0HonWPw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/n8n-nodes-barcode-generator/v/1.0.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-008253","import_time":"2026-07-08T19:33:49.857873283Z","modified_time":"2026-07-08T19:30:21Z","sha256":"eb55ae2b864b933ae071cb33e8f53a52005ff0dc26487d15639f3b07fa7d9849","source":"amazon-inspector","versions":["1.0.3"]}]}}
