Project: Open Social [1]
Date: 2022-November-30
Security risk: *Moderately critical* 13∕25
AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon [2]
Vulnerability: Access bypass

Affected versions: >=11.4.0 <11.4.9 || >=11.5.0 <11.5.1
Description: 
Social Flexible Group is an Open Social extension that allows users to create
groups with many different configurations.

In specific uncommon scenarios, where a platform doesn't have any flexible
groups with the "Group members only (secret)" visibility, community groups
are visible to anonymous users on the /all-groups page. No other group
information is revealed since group access is not affected by this issue.

This vulnerability is mitigated by creating a Flexible Group with visibility
"Group members only (secret)".

Solution: 
Install the latest version:

   * If you use the Open Social distribution for Drupal 9.x, upgrade to Open
     Social 11.5.1 [3]
   * If you use the Open Social distribution for Drupal 9.x, upgrade to Open
     Social 11.4.9 [4]
