Affected versions of this package are vulnerable to Insufficiently Protected Credentials via the HTTP response handling logic that sets the X-Session-ID header. An attacker can hijack user sessions by observing session identifiers leaked in HTTP response headers, as the server exposes active session tokens outside the intended trust boundary, enabling unauthorized reuse of valid sessions.
