AI-suggested

Upgrade Kiteworks Core to version 9.5.0 or later where this vulnerability is fixed. Since this is not a cloud service, remediation requires applying the vendor's official patch or update. Patch status is confirmed by the version boundary provided.

Description

Kiteworks Core before version 9.5.0 is vulnerable to Stored Cross-site Scripting (XSS) that could allow an authenticated user to store crafted content that executes arbitrary JavaScript in another user's authenticated session when they preview shared content. This could potentially lead to session compromise and account takeover.
