Miggo AIRoot Cause Analysis

The vulnerability stems from improper path handling in directory redirect logic. When serve-static is mounted at root, requests like //www.google.com/%2e%2e trigger sendRedirect to set Location: //www.google.com/%2e%2e/. Browsers interpret '//' as a protocol-relative URL, enabling open redirects. The sendRedirect function's failure to validate if the normalized path represents an external target makes it the vulnerable component. This matches the PoC behavior and CWE-601 classification.
