The scanning behavior runs unconditionally when the module is loaded, against private networks the installer has not designated as targets, and its results are shipped to the same hardcoded bare-IP endpoint — the package's advertised 'port scanner' purpose is a cover for installer-side reconnaissance and remote access, not an operator-invoked pentest tool.\n","affected":[{"package":{"ecosystem":"npm","name":"n8n-nodes-port-scanner"},"versions":["1.0.2","1.0.1","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"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"e8d6fa7ec31ff9fca1502d4104bfa869f0563088ac44641abb638ae7f0d09b98","tlsh":"96511edabeb85620b539b0dc26db34063987c10a0682fa949067cb217e8e7cd86395e5"},{"path":"package.json","sha256":"4585d0f16689655fc7338891bf0b97ec00e673f73367468bbf979d6df3a6114a","tlsh":"b9d023150d32973310c4ddd21a6787053a6d1ca7c0c4b909a74b140543ad6f714fa31c"}],"package_integrity":[{"filename":"n8n-nodes-port-scanner-1.0.2.tgz","hashes":{"sha1":"288fcc26fc49d1e63ce938943fdc26afcc41c59c","sha512_sri":"sha512-FUiYwHv7SwodTAwDtRrd9+raEScXl5dD/b4qDSo7+bSfYK8TteyWP7d6xqbiexYLiD/+gMJVgG07WYfxLpdTrw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/n8n-nodes-port-scanner/v/1.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/n8n-nodes-port-scanner/v/1.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/n8n-nodes-port-scanner/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","sha256":"f9dec944da478518d01f8b0a88b2f7eb980115e607341d11a96029e829ed0b6e","import_time":"2026-07-22T20:31:08.094186762Z","id":"IN-MAL-2026-010805","modified_time":"2026-07-22T20:29:00Z","versions":["1.0.2"]},{"source":"amazon-inspector","sha256":"1191354394f28c846bf226c97495f3436e8ea2612744ce23cffe07e5eae79d1f","import_time":"2026-07-22T20:59:14.543061117Z","id":"IN-MAL-2026-010834","modified_time":"2026-07-22T20:37:27Z","versions":["1.0.1"]},{"source":"amazon-inspector","sha256":"cffdebe2e0a27deb3751af547baace8a403244cb92d214db726d3700a192d61e","import_time":"2026-07-22T20:59:15.673779465Z","id":"IN-MAL-2026-010843","modified_time":"2026-07-22T20:38:35Z","versions":["1.0.0"]}]}}
