A privilege escalation vulnerability in Kiteworks could have allowed an attacker who had already obtained code execution on one node of a clustered Kiteworks deployment to run operating system commands with elevated privileges on another node of the same cluster. Insufficient input validation in an internal cluster management function let attacker-supplied values reach a privileged execution context; exploitation requires existing access to a node in the cluster, and the affected function is not reachable from outside the cluster.
