Advisory

Source description from Wordfence Intelligence.

The BuddyPress plugin for WordPress is vulnerable to Insufficient Input Validation in versions up to, and including, 6.3.0. This is due to missing authorization checks and proper sanitization on a users profile page. This makes it possible for authenticated attackers to add style attributes to the "span" and "p" elements when using the rich text fields which makes Cross-Site Scripting possible.
