Project: GraphQL [1] Date: 2021-June-02 Security risk: *Moderately critical* 11∕25 AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon [2] Vulnerability: Information Disclosure

Description:  This module lets you craft and expose a GraphQL web service API.

The module does not sufficiently protect arbitrary exception and error messages thereby exposing an information disclosure vulnerability.

This vulnerability is mitigated by the fact that a GraphQL server must be enabled and a data producer be configured that throws exceptions with confidential error messages that must not be exposed over the GraphQL API.

Solution:  Install the latest version:

* If you use the GraphQL module for Drupal 8.x, upgrade to GraphQL 8.x-4.1 [3]

Reported By:  * Alex Tkachev [4]

Fixed By:  * Klaus Purer [5] * Radoslav Terezka [6]

Coordinated By:  * Greg Knaddison [7] of the Drupal Security Team
