The package name also impersonates the Carvana org by using a `.` in the scope (`@carvana.authentication-flows/shared`), making `carvana.authentication-flows` a fake top-level npm scope rather than a Carvana-owned namespace. There is no legitimate functionality shipped; the package's sole effect on install is reconnaissance exfiltration to an attacker-controlled out-of-band server.\n","affected":[{"package":{"ecosystem":"npm","name":"@carvana.authentication-flows/shared"},"versions":["19.2.1"],"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":"9f851a66b1ef4cf2b6543e3b624dc281563a1b69ecf655d6d2eb18b54b5d222e","tlsh":"515151c515f65a241ba7b8494a4f9402a327e103350aee59bfcc8340af9937c97f0bf2"},{"path":"package.json","sha256":"af283088a4067e78c0dedb6c29a896e298d609863cbe5341d39e3fc729b66b1f","tlsh":"48d05e348e616923a6c112b29c2b948673a19f6f04143c0867df682d91de777a8ff35d"}],"package_integrity":[{"filename":"shared-19.2.1.tgz","hashes":{"sha1":"334c51ef3b5ffd32c4738e36b75fabee4089c7cd","sha512_sri":"sha512-U+TTgoHl5oDERgD+meQnLOZ6J2z5gIY9minqyqzmJv8ws3tW10y7CKEj+PCcDajYej1pRMPnrk5iUVuJl5NuXg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@carvana.authentication-flows/shared/v/19.2.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-007608","import_time":"2026-06-26T14:59:21.404970519Z","modified_time":"2026-06-26T14:36:29Z","sha256":"78538bf70d1ebd3e4cd784d90b3961ea7966ce9b97e8124110374cad95c0b894","source":"amazon-inspector","versions":["19.2.1"]}]}}
