This module provides a JSON API standards-compliant API for accessing and manipulating Drupal content and configuration entities.
The module doesn't provide CSRF protection when processing authenticated traffic using cookie-based authentication.
This vulnerability is mitigated by the fact that an attacker must be allowed to create or modify entities of a certain type, and a very specific and uncommon CORS configuration that allows all other pre-checks to be skipped.
Install the latest version:
- If you use the JSON API module for Drupal 8.x, upgrade to 8.x-1.16
