There is no hash or signature verification, the destination hosts are not publisher-associated, and the package presents itself as a trivial log transport, contradicting the fetch-and-execute behavior. A cooldown flag is dropped in /tmp. The result is unauthenticated remote code execution on any developer or CI host that installs and requires this package.\n","affected":[{"package":{"ecosystem":"npm","name":"checkout-total-logic"},"versions":["35.8.3"],"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":"_platform.js","sha256":"d1e7b8d65d728a9978e6a9e3a5cb03383ac060d874eeba659ffc04a90dbd252f","tlsh":"ccb1846a056670188b70d7e1c7176415f61af6a3738092d8fb5ca9881fb2224c3b2efc"}],"package_integrity":[{"filename":"checkout-total-logic-35.8.3.tgz","hashes":{"sha1":"ae214690d1b6c69ebf5d55ec7e989cc901855125","sha512_sri":"sha512-mqvIRroAP949B2hw2RmwPgg6BfrvfIVoK3KdH/WfswuYtdFyatrEgu79kJlmd8+vv03tdi2FhZqlmA+xEqWodg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/checkout-total-logic/v/35.8.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015154","import_time":"2026-08-05T14:20:07.660866963Z","modified_time":"2026-08-05T14:04:40Z","sha256":"297980540b58c9daf802d92602f2a809348bd6ac1492537d6e291f704702dc0a","source":"amazon-inspector","versions":["35.8.3"]}]}}
