Because the dropper is both in the postinstall script and at the top level of the main module, it executes on `npm install` and again every time a consumer `require`s the package or n8n loads the node.\n","affected":[{"package":{"ecosystem":"npm","name":"@years19/n8n-nodes-utils-helper-y"},"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":"2b32e5688aaeb3911c8d3da7927f1569ff2987e60b24c626f0e0295d2f3769e9","tlsh":"1b4188d23eb49574d5b3605099a6de42e727f00b56c2edd8f04dd7b20f5a03427914f4"},{"path":"index.js","sha256":"2b32e5688aaeb3911c8d3da7927f1569ff2987e60b24c626f0e0295d2f3769e9","tlsh":"1b4188d23eb49574d5b3605099a6de42e727f00b56c2edd8f04dd7b20f5a03427914f4"},{"path":"package.json","sha256":"4f4f78adb6a4b4bcef973db4d4b4cd655b0b5fe8f5e74fb449ced53320723aaf","tlsh":"cbf0a3038d720f3311cd6b66185941016b246d87949c7c2c73cf010c87dc6f519bd58d"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-y-1.0.0.tgz","hashes":{"sha1":"d4a99f3fe358bdd2373dcde37d87ee81888b81f5","sha512_sri":"sha512-+jPJON3p89evACyiiJM0rab5RfqSW561aVktqjB5EmEdRBYHx2OObZWMaOjXdKTD+I0emGltdgBl7gBhjBfi1Q=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years19/n8n-nodes-utils-helper-y/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017578","import_time":"2026-08-12T15:26:11.41679628Z","modified_time":"2026-08-12T15:07:21Z","sha256":"39f5f361848c187cd60f9143d0bdc5d2db20a3e2fa03fe5e494697da05c4a42a","source":"amazon-inspector","versions":["1.0.0"]}]}}
