CVE-2026-102101

Kiteworks Core deserialization of untrusted data

Published Sep 30, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
Kiteworks Core before version 9.5.0 is vulnerable to Deserialization of Untrusted Data. A deserialization weakness in Kiteworks Core could, under certain conditions, allow crafted data to be deserialized unsafely, potentially resulting in remote code execution on the appliance. Exploitation depends on an attacker first being able to influence the affected data, so this issue is not exploitable on its own.
