High · 8.1 Known exploited Scanner template Public exploit CVE-2019-6340 DRUPAL-CORE-2019-003EUVD-2022-2184GHSA-3gx6-h57h-rm27

Drupal core - Highly critical - Remote Code Execution

Published Feb 21, 2019 · Updated Oct 21, 2025 · Assigned by drupal

Vendor: Drupal Product: Drupal core Package: drupal/core Package: drupal/drupal Category: Web / CMS Ecosystem: Packagist

Description

Some field types do not properly sanitize data from non-form sources in Drupal 8.5.x before 8.5.11 and Drupal 8.6.x before 8.6.10. This can lead to arbitrary PHP code execution in some cases. A site is only affected by this if one of the following conditions is met: The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows PATCH or POST requests, or the site has another web services module enabled, like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupal 7. (Note: The Drupal 7 Services module itself does not require an update at this time, but you should apply other contributed updates associated with this advisory if Services is in use.)
