Description
CVE-2026-102136 is a vulnerability in Kiteworks Core affecting multi-node deployments. An attacker with code execution on one node can submit crafted input via an internal cluster interface, which is insufficiently validated when written into monitoring configuration on another node. This can lead to execution of OS commands under an unprivileged service account on the second node. The vulnerability is classified as a CRLF injection (CWE-93) and impacts versions prior to 9.5.1. The CVSS score is 6.3, indicating a medium severity.
