Authentication Bypass

Description

### Impact An authenticated user can overwrite server-generated session fields (`sessionToken`, `expiresAt`, `createdWith`) when creating a session object via `POST /classes/_Session`. This allows bypassing the server's session expiration policy by setting an arbitrary far-future expiration date. It also allows setting a predictable session token value. ### Patches The session creation endpoint now filters out server-generated fields from user-supplied data, preventing them from being overwritten. ### Workarounds Add a `beforeSave` trigger on the `_Session` class to validate and reject or strip any user-supplied values for `sessionToken`, `expiresAt`, and `createdWith`.
