CVE-2017-16131: Directory Traversal in unicorn-list

The provided vulnerability information and references do not include actual source code snippets, commit diffs, or specific function names from the 'unicorn-list' package. While the vulnerability mechanism (improper path sanitization leading to directory traversal) is clear, the lack of concrete implementation details makes it impossible to identify specific vulnerable functions with high confidence. Typically, such vulnerabilities would involve functions handling request URI resolution or file system operations (e.g., fs.readFile in Node.js), but without access to the package's code structure, we cannot definitively name these functions or their file paths.
