The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to second-order SQL Injection via filenames in all versions up to, and including, 2.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with access to upload files and manage filenames through a third-party plugin like a File Manager, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The risk of this vulnerability is very minimal as it requires a user to be able to manipulate filenames in order to successfully exploit.
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.9.1 through different error messages in the responses. This makes it possible for unauthenticated attackers to exfiltrate data from wp_usermeta table.
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to time-based SQL Injection via the search parameter in all versions up to, and including, 2.9.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to unauthorized profile picture updates due to a missing capability check on the wp_ajax_um_resize_image() and ajax_resize_image() functions in all versions up to, and including, 2.8.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the profile pictures of other users.
