Actively exploited Drupal Core vulnerability, High severity, CVSS 8.1. Added to the CISA KEV catalog 2022-03-25.
Senserva AI Opinion for CVE-2019-6340
This Drupal Core flaw stems from field types that fail to sanitize data from non-form sources like REST or JSON:API, allowing arbitrary PHP code execution. Any Drupal 8 site with RESTful web services or the JSON:API module enabled and accepting write requests is exposed, and CISA confirmed active exploitation in the wild. With a 92 percent EPSS score, unpatched public sites are being targeted.
Do this: Apply the Drupal Core security update immediately and, if patching must wait, disable all web services modules or block PUT, PATCH, and POST requests to REST endpoints.
