Any caller invoking the exported function grants the remote endpoint arbitrary code execution in the Node.js process with full host privileges. The endpoint is disguised with icon/CDN vocabulary (iconDomain, font-awesome/svgs/brands, a 'bearrtoken' field literal 'logo') and an unused IconProvider map, while the package advertises itself as a 'custom API library' — the icon framing is cover for the fetch-and-eval path. The payload is mutable, unpinned, unauthenticated, and served over a bare-IP host unrelated to any legitimate publisher infrastructure.\n","affected":[{"package":{"name":"poly-custom-api","ecosystem":"npm"},"versions":["5.3.1"],"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":"index.js","sha256":"ce2c680ca6b7355d73cbc131465fc6b2f2508f367b57ecb27a3b05e6e247213f","tlsh":"30c1616546fa31a36a67e4eef30f10027165e313365de971f48e42902fca568e5f24e8"}],"package_integrity":[{"filename":"poly-custom-api-5.3.1.tgz","hashes":{"sha1":"09dc2e523079cf687c0330e52558c97354e5abca","sha512_sri":"sha512-RSR9waszWVq+MZd+I7SpD7Nl7L6rKVM8CLcLlEFXtKV+xAPt8oAbFca1z/EzyOvr86tGaRVXFTURXE/9vScfeA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/poly-custom-api/v/5.3.1"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014848","import_time":"2026-08-05T13:08:50.870521254Z","modified_time":"2026-08-05T13:01:01Z","sha256":"a3263a9e2a986068fafa530a8e6862f9ba41cad05ecbd5b7b91752ca1c5af0c6","source":"amazon-inspector","versions":["5.3.1"]},{"id":"RLMA-2026-10777","import_time":"2026-09-24T09:21:35.331713104Z","modified_time":"2026-09-22T17:36:19Z","sha256":"844e3e52bd0aba032142b3cc4455f99416b4375d4ba9d5a0862fc96b926884fc","source":"reversing-labs","versions":["5.3.1"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"ReversingLabs","contact":["https://www.reversinglabs.com"],"type":"FINDER"}]}
