CVE-2026-102136 · Severity: medium · CVSS 6.3 · Published 2026-09-30

Kiteworks Core is a secure file sharing and content management appliance used by enterprises to protect sensitive data. In multi-node cluster deployments, an attacker with code execution on one node can inject malicious values into monitoring configuration on other nodes, leading to arbitrary OS command execution. The impact is limited to the unprivileged service account running the monitoring process, reducing but not eliminating the risk of system compromise and lateral movement.

## Technical details

The vulnerability exists in multi-node Kiteworks Core deployments where an internal cluster interface accepts configuration values without proper validation. An attacker with existing code execution on one appliance node can craft malicious input through this interface that gets written into monitoring configuration files on other nodes, leading to command injection. The attacker must already have local or code execution privileges on at least one node, and command execution is constrained to an unprivileged service account.
