Description

CVE-2019-6340 is a remote code execution vulnerability in Drupal Core where certain field types fail to properly sanitize data from non-form sources, potentially allowing arbitrary PHP code execution. This vulnerability has been exploited in the wild. It is classified as high severity due to the risk of remote code execution.

Summary
