| 説明 | An authenticated user can read the contents of any email thread in the system by sending a single PATCH request that pivots their ThreadAccess record from a thread they legitimately own to an arbitrary target thread. The permission check validates the thread before the update; the serializer writes the new thread value without re-checking authorization.
Any authenticated user in a multi-tenant deployment can exfiltrate the complete contents of any other user's threads without the knowledge of the victim.
This includes private correspondence, board-level discussions, attachments, and any other content stored as email threads |
