Prior to version 5.9.2, SQL injection can occur when the non-default simple protocol is used, a dollar quoted string literal is used in the SQL query, that string literal contains text that would be would be interpreted as a placeholder outside of a string literal, and the value of that placeholder is controllable by the attacker. This issue has been patched in version 5.9.2."

Antes de la versión 5.9.2, puede ocurrir una inyección SQL cuando se utiliza el protocolo simple no predeterminado, se utiliza un literal de cadena entre comillas de dólar en la consulta SQL, ese literal de cadena contiene texto que sería interpretado como un marcador de posición fuera de un literal de cadena, y el valor de ese marcador de posición es controlable por el atacante. Este problema ha sido parcheado en la versión 5.9.2."
