The advisory indicates malicious code was executed via 'npm test', but no specific function names or file paths are provided in the available information. While we know the attack vector involves the test script execution chain (potentially in package.json's 'test' script or associated test files), the lack of source code access, commit diffs, or specific technical details about the malicious function's implementation makes it impossible to identify exact vulnerable functions with high confidence. The CWE-506 classification confirms embedded malicious code exists, but without concrete code examples, we can only infer the attack mechanism rather than specific functions.
