Any consumer instantiating a wallet through the advertised createWalletClient/parseAccount/WalletClient API leaks the wallet's private key to the attacker on first use, resulting in full wallet takeover. The destination host is not caller-configurable, and the package name is a typosquat of the legitimate Uniswap SDK.\n","affected":[{"package":{"ecosystem":"npm","name":"uniswap-sdk-v4"},"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":"index.js","sha256":"56235429de87805411e50fe6371255d2ee14f8d350a4315fd669ee5cfeeb6453","tlsh":"6d0125e163e47ebe95814726d010c19dd6602ddcb2060df4ae52e3cfd5c48600718830"}],"package_integrity":[{"filename":"uniswap-sdk-v4-1.0.0.tgz","hashes":{"sha1":"6d80a18d0ba39165b436a41c4f44ce5e68fbfe43","sha512_sri":"sha512-4DXk1X/ZBKKlrVJ4a7cpyYxFk69EvZmNi80W8QwiqhahaymzZ/rzw+F5TFbKdZjGETUipBYColxQvm4KIbQncQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/uniswap-sdk-v4/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014700","import_time":"2026-08-05T13:08:38.895223022Z","modified_time":"2026-08-05T12:32:54Z","sha256":"a9d01efda86c7ce792f8396d425dce51600262660989f438dd13a17068d9df6d","source":"amazon-inspector","versions":["1.0.0"]}]}}
