CVE-2026-14453: Centreon Infra Monitoring lets low‑privilege users execute code
CVE-2026-14453 · published 4 months ago
Summary
A feature in the open‑tickets component of Centreon Infra Monitoring stores a user‑provided message without checking it, and then displays it using a template engine. This lets any logged‑in user add malicious content that can run commands on the server, exposing secrets and potentially disrupting the monitoring service. Apply the latest vendor update or disable the open‑tickets module until a fix is installed, and restrict access to trusted users.
What to do
- Update centreon infra monitoring to version 24.10.14 or later.

Original advisory text
A user with low privileges can inject SSTI templates that can lead to RCE in open-tickets
This vulnerability is a critical Server-Side Template Injection (SSTI) in Centreon's centreon-open-tickets module that leads to Remote Code Execution. The message_confirm field is stored without sanitization and rendered via Smarty with no security policy enabled, allowing any authenticated user, to inject and execute arbitrary code on the server. This results in disclosure of environment secrets and could impact platform availability of Centreon Infra Monitoring product.
