Vulnerability details
The vulnerability allows a remote user to obtain broader node authority than intended.
The vulnerability exists due to a time-of-check time-of-use race condition in the node pairing reconnection feature when handling paired or reconnecting node sessions. A remote user can manipulate pairing state transitions to obtain broader node authority than intended.
Only instances with the affected feature enabled and reachable are vulnerable. Practical impact depends on operator configuration and whether lower-trust input can reach the affected path.
