## Description

The Media Library Assistant plugin for WordPress is vulnerable to SQL Injection via the 'mla-metavalue' parameter in all versions up to, and including, 3.43, due to the user-supplied value (when it begins with a space) being spliced back into the query's WHERE clause with preg_replace in mla_query_posts_where_filter() without escaping or preparation. This makes it possible for authenticated attackers with author-level access and above, who can reach the Media/Assistant admin screen, to append additional SQL queries to existing queries and extract sensitive information from the database.
