Vulnerability details
The vulnerability allows a remote user to modify session object properties of another user and disclose custom fields from that session object.
The vulnerability exists due to improper access control in the _Session class when handling write requests for session objects with a known object ID. A remote user can update the user field of a foreign session object to read custom fields from that session object.
The issue only affects foreign session objects. It may be possible to brute-force guess a valid session object ID, and the impact may be greater in deployments that use custom logic to relate specific session objects to privileges.
