Parse Server exposes auth data via /users/me endpoint
Details
### Impact
An authenticated user calling `GET /users/me` receives unsanitized auth data, including sensitive credentials such as MFA TOTP secrets and recovery codes. The endpoint internally uses master-level authentication for the session query, and the master context leaks through to the user data, bypassing auth adapter sanitization. An attacker who obtains a user's session token can extract MFA secrets to generate valid TOTP codes indefinitely.
### Patches
The `/users/me` endpoint now queries the session and user data separately, using the caller's authentication context for the user query so that all security layers apply correctly.
### Workarounds
There is no known workaround.
