Technical details

The Ultimate Member plugin for WordPress is vulnerable to blind SQL Injection via the 'search' parameter in the member directory component. This issue exists in versions up to and including 2.10.1 due to insufficient escaping of user-supplied input and a lack of proper SQL query preparation. An unauthenticated remote attacker can exploit this by appending malicious SQL commands to existing queries. This allows for the extraction of sensitive data from the database through inference (blind SQLi). The vulnerability is a regression or incomplete fix related to a previous patch in version 2.9.2.
