Moodle stored Cross-site Scripting (XSS)

CVE-2024-33997GHSA-9qgq-93c7-9hm4

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (moodle/moodle 4.3.4, 4.2.7, 4.1.10), 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-2024-33997

Advisory: Moodle stored Cross-site Scripting (XSS)
IDs: CVE-2024-33997, GHSA-9qgq-93c7-9hm4
Record: https://patchnext.com/advisories/cve-2024-33997 (revision 1, source checked 26 Oct 2026, 14:33 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: moodle/moodle 4.3.4, 4.2.7, 4.1.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist moodle/moodle: affected >= 4.3.0, < 4.3.4; >= 4.2.0, < 4.2.7; < 4.1.10; fixed in 4.3.4, 4.1.10, 4.2.7

## Suggested inspection (read-only)
- Packagist moodle/moodle: 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 moodle/moodle.
- 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
