Drupal Core Cross-Site Scripting (XSS) Vulnerability

CVE-2025-31675GHSA-m4wj-hhwj-47qp

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (drupal/core 11.1.5, 11.0.13, 10.4.5, 10.3.14), 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-2025-31675

Advisory: Drupal Core Cross-Site Scripting (XSS) Vulnerability
IDs: CVE-2025-31675, GHSA-m4wj-hhwj-47qp
Record: https://patchnext.com/advisories/cve-2025-31675 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 1.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: drupal/core 11.1.5, 11.0.13, 10.4.5, 10.3.14. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist drupal/core: affected >= 8.0.0, < 10.3.14; >= 10.4.0, < 10.4.5; >= 11.0.0, < 11.0.13; >= 11.1.0, < 11.1.5; fixed in 11.0.13, 11.1.5, 10.3.14, 10.4.5

## Suggested inspection (read-only)
- Packagist drupal/core: 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 drupal/core.
- 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
- Verified: https://github.com/advisories/GHSA-m4wj-hhwj-47qp (GitHub-reviewed advisory GHSA-m4wj-hhwj-47qp lists affected ranges: Packagist drupal/core >=8.0.0 =10.4.0 =11.0.0 =11.1.0 <11.1.5)

Commands are suggestions: review each one before running it.
