Miggo AIRoot Cause Analysis

The vulnerability stems from improper path resolution when handling HTTP requests. The advisory explicitly states the server resolves relative paths without sanitization. In Node.js servers, this typically occurs in the request handler where req.url is concatenated with the root directory (e.g., via path.join or path.resolve) without subsequent validation to ensure the resolved path stays within the root. Functions like fs.readFile are then called with this tainted path. While the exact code isn't available, this pattern matches the described vulnerability and is consistent with CWE-22.
