Moodle has a CSRF risk in user tours manager that allows tour duplication

CVE-2025-3635GHSA-88xj-97gf-7wpq

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (moodle/moodle 4.5.4, 4.4.8, 4.3.12, 4.1.18), 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-2025-3635

Advisory: Moodle has a CSRF risk in user tours manager that allows tour duplication
IDs: CVE-2025-3635, GHSA-88xj-97gf-7wpq
Record: https://patchnext.com/advisories/cve-2025-3635 (revision 1, source checked 26 Oct 2026, 14:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: moodle/moodle 4.5.4, 4.4.8, 4.3.12, 4.1.18. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist moodle/moodle: affected < 4.1.18; >= 4.3.0-beta, < 4.3.12; >= 4.4.0-beta, < 4.4.8; >= 4.5.0-beta, < 4.5.4; fixed in 4.4.8, 4.1.18, 4.5.4, 4.3.12

## 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.
