Vulnerability in Kiteworks Core
CVE-2026-102125
The sandbox that isolates document conversion on a Kiteworks appliance did not fully confine the code running inside it. Code already executing within that sandbox could potentially escape its confinement and act with the privileges of the service account that runs the application, which could allow an attacker in that position to read or modify application data and configuration, or to disrupt the service on the affected appliance.
