Centreon contains cross-site scripting vulnerability via esc_name parameter

CVE-2022-40044GHSA-rv5q-72p2-2q24

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (centreon/centreon 22.04.1, 21.10.8, 21.04.16), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2022-40044

Advisory: Centreon contains cross-site scripting vulnerability via esc_name parameter
IDs: CVE-2022-40044, GHSA-rv5q-72p2-2q24
Record: https://patchnext.com/advisories/cve-2022-40044 (revision 1, source checked 26 Oct 2026, 14:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: centreon/centreon 22.04.1, 21.10.8, 21.04.16. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist centreon/centreon: affected < 21.04.16; >= 21.10.0, < 21.10.8; >= 22.0.0, < 22.04.1; fixed in 21.04.16, 22.04.1, 21.10.8

## Suggested inspection (read-only)
- Packagist centreon/centreon: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on centreon/centreon.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
