CVE-2026-108515

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (drupal/core 12.0.0-beta2, 11.4.10, 11.3.19, 10.6.19), 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.

Source description

As published by the source; long descriptions are shortened.

The Drupal core Link module provides a field type that can be used for internal and external URLs. The module does not sufficiently sanitize certain markup in some circumstances, which can lead to cross-site scripting (XSS) vulnerabilities.

# Patch Next advisory brief: CVE-2026-108515

Advisory: DRUPAL-CORE-2026-015
IDs: CVE-2026-108515
Record: https://patchnext.com/advisories/cve-2026-108515 (revision 1, source checked 23 Oct 2026, 22:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: drupal/core 12.0.0-beta2, 11.4.10, 11.3.19, 10.6.19. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist drupal/core: affected >= 8.9.0, < 10.6.19; >= 11.0.0, < 11.3.19; >= 11.4.0, < 11.4.10; >= 12.0.0-alpha1, < 12.0.0-beta2; fixed in 10.6.19, 11.3.19, 11.4.10, 12.0.0-beta2

## 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
