Project: Open Social [1] Date: 2021-June-02 Security risk: *Critical* 15∕25 AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Authentication Bypass

Description:  Open Social is a Drupal distribution for online communities.

The included social_magic_login module doesn't sufficiently validate magic login URLs for user accounts. The lack of validation makes it possible for an adversary to forge valid login URLs and login to such an account.

This vulnerability is mitigated by the fact the module social_magic_login needs to be enabled.

Solution:  Install the latest version of Open Social:

* If you use the Open Social distribution for Drupal 10.0.x, upgrade to Open Social 10.0.13 [3] * If you use the Open Social distribution for Drupal 10.1.x, upgrade to Open social 10.1.6 [4]

Alternatively, disable the module social_magic_login.
