Drupal · Drupal · CVE-2019-6340
**Name of the Vulnerable Software and Affected Versions**
Drupal versions 8.5.x before 8.5.11
Drupal versions 8.6.x before 8.6.10
**Description**
Some field types do not properly sanitize data from non-form sources in Drupal. 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.
**Recommendations**
For Drupal 8.5.x, update to version 8.5.11 or later.
For Drupal 8.6.x, update to version 8.6.10 or later.
As a temporary workaround, consider disabling the RESTful Web Services (rest) module until a patch is available.
Restrict access to the vulnerable module `rest` to minimize the risk of exploitation.
Avoid using the `PATCH` or `POST` requests in the affected API endpoints until the issue is resolved.
