CWE-ID: CWE-863 - Incorrect Authorization

The vulnerability allows a remote user to disclose protected session fields.

The vulnerability exists due to incorrect authorization in the GET /sessions/me endpoint when handling requests for the caller's session. A remote user can send a request to retrieve protected session fields.

The issue affects the /sessions/me endpoint, while the equivalent /sessions and /sessions/:objectId endpoints correctly strip protected fields.
