The BuddyBoss Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Group Name in all versions up to, and including, 3.6.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the "Enable social group creation by all members" setting to be enabled, which is the default and permits Subscriber-level users to create groups; exploitation is not possible if group creation is restricted to administrators.
