CVE-2026-14453Network attack vector

Authenticated code execution via unsafe Smarty rendering

Published Jul 13, 2026 · Updated Jul 13, 2026

Server-side template injection in Centreon Open Tickets allows remote authenticated users to execute arbitrary code through crafted ticket text. The module stores message_confirm without sanitization and passes it to Smarty for rendering without an enabled security policy. The issue affects 24.10.0 through 24.10.13 and 25.10.0 through 25.10.8; any authenticated account can read environment secrets and interrupt monitoring through executed code.
