Summary

The Groups plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.0 via the 'group_id' parameter of the group_join function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to register for groups other than ones set in the shortcode.

Risk Assessment

Attackers can join unauthorized groups, potentially leading to unauthorized access to content or features. The risk affects all sites with the vulnerable plugin installed.

Recommendation

Update the Groups plugin to the latest version that fixes the vulnerability. If updating is not possible, consider disabling the plugin until a patch is released.
