View online: https://www.drupal.org/sa-contrib-2021-003 Project: Subgroup [1] Version: 1.0.x-dev Date: 2021-January-27 Security risk: *Less critical* 9∕25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Uncommon [2] Vulnerability: Access bypass Description: This module enables you to add groups to other groups in a tree structure where access can be inherited up or down the tree. When you configure Subgroup to have a tree with at least three levels, users may inadvertently get permissions in a group that is an uncle or cousin of the source group, rather than a direct ancestor or descendant. Trees with only multiple nodes at the lowest tier (or nowhere) are unaffected. Solution: Install the latest version, Subgroup 1.0.1 [3], and clear your caches.

Open Social - Moderately critical - Access bypass - SA-CONTRIB-2021-002

View online: https://www.drupal.org/sa-contrib-2021-002 Project: Open Social [1] Version: 8.x-9.x-dev8.x-8.x-dev Date: 2021-January-27 Security risk: *Moderately critical* 10∕25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Default [2] Vulnerability: Access bypass Description: The Social User Export module enables users within Open Social to create an export of users and download this to a CSV file. The module doesn't sufficiently check access when building the CSV file, allowing logged-in users without the manage members permission to be able to export all data from a selected user in certain scenarios. This vulnerability is mitigated by the fact that an attacker must have the authenticated user role and the site must have the configuration set in such a way a logged in user is able to export users. Solution: Install the latest version: * If you use Open Social major version 8, upgrade to 8.x-8.10 [3] * If you use Open Social major version 9, upgrade to 8.x-9.8 [4] Reported By: * Robert Ragas [5] Fixed By: * Ronald te Brake [6] * Alexander Varwijk [7] * Bram ten Hove [8] Coordinated By: * Greg Knaddison [9] 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/8.x-8.10 [4] https://www.drupal.org/project/social/releases/8.x-9.8 [5] https://www.drupal.org/user/2723261 [6] https://www.drupal.org/user/2314038 [7] https://www.drupal.org/user/1868952 [8] https://www.drupal.org/user/1549848 [9] https://www.drupal.org/user/36762

Open Social - Moderately critical - Access bypass - SA-CONTRIB-2021-001

View online: https://www.drupal.org/sa-contrib-2021-001 Project: Open Social [1] Version: 8.x-9.x-dev8.x-8.x-dev Date: 2021-January-27 Security risk: *Moderately critical* 12∕25 AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2] Vulnerability: Access bypass Description: The optional Social Auth Extra module enables you to use the single sign-on methods provided by Open Social e.g. Facebook, LinkedIn, Google and Twitter. The module doesn't implement a proper cache strategy for anonymous users allowing the registration form to be cached with disclosed information in certain scenarios. The information is usually only available for logged-in users of the community. This vulnerability is mitigated by the fact that social_auth_extra needs to be enabled, one of the single sign-on methods needs to be configured. There is no impact for regular registration without single sign-on. Removing the single sign-on providers from configuration will allow this vulnerability to be blocked. Solution: Install the latest version: * If you use Open Social major version 8, upgrade to 8.x-8.10 [3] * If you use Open Social major version 9, upgrade to 8.x-9.8 [4] Reported By: * Alexander Varwijk [5] Fixed By: * Alexander Varwijk [6] * Ronald te Brake [7] Coordinated By: * 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/8.x-8.10 [4] https://www.drupal.org/project/social/releases/8.x-9.8 [5] https://www.drupal.org/user/1868952 [6] https://www.drupal.org/user/1868952 [7] https://www.drupal.org/user/2314038 [8] https://www.drupal.org/user/36762

For more information please see: * CVE-2020-36193 [3] Exploits may be possible if Drupal is configured to allow .tar, .tar.gz, .bz2, or .tlz file uploads and processes them. Solution: Install the latest version: * If you are using Drupal 9.1, update to Drupal 9.1.3 [4]. * If you are using Drupal 9.0, update to Drupal 9.0.11 [5]. * If you are using Drupal 8.9, update to Drupal 8.9.13 [6]. * If you are using Drupal 7, update to Drupal 7.78 [7]. Versions of Drupal 8 prior to 8.9.x are end-of-life and do not receive security coverage. Disable uploads of .tar, .tar.gz, .bz2, or .tlz files to mitigate the vulnerability.
