CVE-2026-102142 · Severity: high · CVSS 7.2 · Published 2026-09-30

Kiteworks Core, a secure file transfer and collaboration appliance, uses a template engine to render system notifications. An authenticated System Administrator can inject malicious template expressions into notification templates that execute arbitrary operating-system commands on the appliance when notifications are sent, giving an attacker complete control over the system.

## Technical details

A server-side template injection vulnerability exists in the system notification template rendering engine. An authenticated System Administrator with template management privileges can store a crafted template containing template expressions that the engine evaluates, leading to remote code execution on the appliance. The vulnerability requires high-privilege authentication but no additional user interaction once the malicious template is created and a notification is triggered.
