Groups plugin for WordPress <3.7.0 - Insecure Direct Object Reference

Title source: llm
STIX 2.1

Description

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.
