Since the vulnerable function is internal and requires existing node access, limiting access to cluster nodes and monitoring for unauthorized node access may reduce risk until a fix is available.
Description
CVE-2026-102120 is a high-severity OS command injection vulnerability in Kiteworks Core affecting versions before 9.5.1. It allows an attacker with existing code execution on one cluster node to escalate privileges and execute OS commands on other nodes within the same cluster. The flaw arises from insufficient input validation in an internal cluster management function, which is not accessible externally and requires prior node access.
