If you cannot patch yet, restrict access to the appliance and sandbox environment to trusted users only to reduce risk.

Description

CVE-2026-102125 is a high-severity vulnerability in Kiteworks Core where the sandbox used for document conversion does not fully isolate the code running inside it. This allows code executing within the sandbox to escape confinement and operate with the privileges of the service account running the application. Exploitation could enable an attacker to read or modify application data and configuration or disrupt the service on the affected appliance.
