CVE-2026-102100
highKiteworks Core before version 9.5.0 is vulnerable to Stored Cross-Site Scripting.
Vendor / product: Accellion — kiteworks
Kiteworks Core before version 9.5.0 is vulnerable to Stored Cross-Site Scripting. A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an authenticated user to submit content that, when later viewed by another user, executes arbitrary JavaScript in that user's authenticated session. This could be used to perform actions on the victim's behalf and may have permitted account takeover, including of higher-privileged users. Exploitation requires the victim to view the attacker-supplied content.
