CVE-2026-102135

6.6 medium SSVC exploitation: none Analyzed
NVD · CVE.org

On a Kiteworks Email Protection Gateway cluster with database replication enabled, a party trusted by the cluster could submit a crafted serialized object that was deserialized without sufficient validation, potentially allowing code execution as the gateway service account. Replication is disabled by default, and exploitation requires control of a trusted cluster peer or administrative access to the appliance.
