Project: Thunder [1]
Date: 2023-March-01
Security risk: *Moderately critical* 13∕25
AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon [2]
Vulnerability: Access bypass

Affected versions: >=6.4.0 <6.4.6 || >=6.5.0 <6.5.3
Description: 
Thunder is a Drupal distribution for professional publishing. The thunder
distribution ships the thunder_gqls module which provides a graphql
interface.

The module doesn't sufficiently check access when serving user data via
graphql leading to an access bypass vulnerability potentially exposing email
addresses.

Solution: 
Install the latest version:

  * If you use the thunder distribution for Drupal 9.x and have the
    thunder_gqls module enabled, upgrade to thunder 6.4.6 [3] or thunder 
6.5.3
    [4] respectively.
