Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin < 2.13.0 - Unauthenticated Unapproved Comment and Private Profile Data Disclosure
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to 2.13.0. This is due to missing approval status filter and profile visibility check in the get_comments() calls inside add_comments() and load_comments(). This makes it possible for unauthenticated attackers to read unapproved comments and activity from private profiles without authentication.
