The Dynific Addons for Elementor plugin for WordPress is vulnerable to SQL Injection via the 'q' parameter in versions up to, and including, 1.3. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the ae_preview_post() AJAX handler and its preview_post_filter() posts_where callback, where the value is passed through $wpdb->esc_like() (addcslashes for '_%\\') and concatenated into a single-quoted SQL LIKE literal — a construction that does not escape single quotes and actively escapes the backslash wp_magic_quotes places before the attacker's quote, freeing it to terminate the literal. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
