View online: https://www.drupal.org/sa-contrib-2024-005 Project: Open Social [1] Date: 2024-January-24 Security risk: *Moderately critical* 13∕25 AC:None/A:User/CI:Some/II:None/E:Proof/TD:Default [2] Vulnerability: Information Disclosure Affected versions: <12.0.5 Description:  Open Social is a Drupal distribution for online communities. The included optional social_group_flexible_group module doesn't sufficiently validate group updates. The lack of validation makes it possible to have content inside the group changing it's visibility, which could lead to that content being shown to a broader audience than intended. This vulnerability is mitigated by the fact the module social_group_flexible_group needs to be enabled. Solution:  Install the latest version of Open Social: * If you use the Open Social distribution for Drupal 12.x, upgrade to Open Social 12.0.5 [3] Reported By:  * Taras Kruts [4] Fixed By:  * Taras Kruts [5] * Ronald te Brake [6] Coordinated By:  * Damien McKenna [7] of the Drupal Security Team * Greg Knaddison [8] of the Drupal Security Team [1] https://www.drupal.org/project/social [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/social/releases/12.0.5 [4] https://www.drupal.org/user/1449610 [5] https://www.drupal.org/user/1449610 [6] https://www.drupal.org/user/2314038 [7] https://www.drupal.org/user/108450 [8] https://www.drupal.org/user/36762
