Path Traversal in Kiteworks Core

CVE-2026-102123

A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching it depends on either the transient window while an appliance is first being provisioned or a non-default appliance configuration.
