Project: JSON API [1] Version: 8.x-1.15 Date: 2018-April-25 Security risk: *Moderately critical* 11∕25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: Cross Site Request Forgery

Description:  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.

Solution:  Install the latest version:

* If you use the JSON API module for Drupal 8.x, upgrade to 8.x-1.16 [3]
