Centreon Sensitive Data Exposure vulnerability

CVE-2020-10945GHSA-h5qv-p378-3hhr

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (centreon/centreon 19.10.7, 19.04.10, 18.10.11, 2.8.32), 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-2020-10945

Advisory: Centreon Sensitive Data Exposure vulnerability
IDs: CVE-2020-10945, GHSA-h5qv-p378-3hhr
Record: https://patchnext.com/advisories/cve-2020-10945 (revision 1, source checked 26 Oct 2026, 14:06 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: centreon/centreon 19.10.7, 19.04.10, 18.10.11, 2.8.32. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist centreon/centreon: affected >= 19.10.0, < 19.10.7; >= 19.0.0, < 19.04.10; >= 18.0.0, < 18.10.11; < 2.8.32; fixed in 2.8.32, 18.10.11, 19.04.10, 19.10.7

## 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.
