CVE-2017-16159: Directory Traversal in caolilinode

The provided vulnerability information does not include concrete code snippets, commit diffs, or explicit references to specific functions in the caolilinode package. While the vulnerability is clearly described (directory traversal via improper path resolution), the lack of access to the actual implementation details (e.g., HTTP request handlers, file path resolution logic) makes it impossible to identify specific vulnerable functions with high confidence. The root cause likely resides in functions that process user-supplied URLs and resolve filesystem paths without proper sanitization, but no explicit function names or file paths are disclosed in the available data.
