CVE-2026-102121

High

Description

A form-rendering interface in the Advanced Forms component is reachable without authentication so that published forms can be displayed to anonymous visitors, but it returned more data than the form itself required. Anyone who knew the web address of a published form could potentially retrieve the form owner's Kiteworks account profile, including personal details, along with parts of the deployment's configuration settings; no passwords, authentication tokens, or multi-factor secrets were exposed.
