View online: https://www.drupal.org/sa-contrib-2018-021 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] Reported By:  * Mateu Aguiló Bosch (e0ipso) [4] Fixed By:  * Mateu Aguiló Bosch (e0ipso) [5] * Wim Leers [6] * Daniel Wehner (dawehner) [7] * Gabe Sullice [8] Coordinated By:  * Michael Hess [9] of the Drupal Security Team [1] https://www.drupal.org/project/jsonapi [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/jsonapi/releases/8.x-1.16 [4] https://www.drupal.org/user/550110 [5] https://www.drupal.org/user/550110 [6] https://www.drupal.org/user/99777 [7] https://www.drupal.org/user/99340 [8] https://www.drupal.org/user/2287430 [9] https://www.drupal.org/u/mlhess
