Known exploited vulnerability
CVE-2019-6340
The short answer
CVE-2019-6340 affects Drupal Drupal Core and is rated high (CVSS 8.1). CISA added it to the Known Exploited Vulnerabilities catalog on 2022-03-25: attackers are using it, so patch it first. Fixed versions are published for drupal/core (8.6.10, 7.62.0, 8.5.11) and drupal/drupal (7.62.0, 8.5.11, 8.6.10).
What it is
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.)
Weakness: CWE-502.
