An attacker can exploit this by submitting double-encoded URLs to access protected routes such as /admin or /api/internal, enabling unauthorized access to restricted functionality.

    Note: There has been an attempt to fix this vulnerability in version 5.15.8 following CVE-2025-64765, but the fix is insufficient.
