Details

The WP Ticket plugin for WordPress is vulnerable to SQL Injection via the WordPress search query parameter (s) in versions up to, and including, 6.0.4 The plugin hooks WordPress's posts_request filter with wp_ticket_com_posts_request(), which calls emd_author_search_results() when the current request is an unauthenticated front-end search. That function reads $query->query_vars['s'] — already wp_unslash()'d by WP_Query::parse_query(), so wp_magic_quotes protection has been stripped — and concatenates the raw value into a SQL LIKE clause inside a UNION sub-SELECT appended to the main query, with no $wpdb->prepare() or escaping. This makes it possible for unauthenticated attackers to append additional SQL queries into already-existing queries that can be used to extract sensitive information from the database.

Severity
