      "value": "Flight is an extensible micro-framework for PHP. Prior to 3.18.1, SimplePdo::insert(), SimplePdo::update(), and SimplePdo::delete() build SQL statements by concatenating the $table argument and the keys of the $data array directly into the query, with no identifier quoting and no validation. When an application forwards user-controlled data shapes to these helpers — a common and documented pattern, e.g. $db->insert('users', $request->data->getData()) — an attacker can inject arbitrary SQL by crafting malicious array keys. This vulnerability is fixed in 3.18.1."

      "value": "Flight es un micro-framework extensible para PHP. Antes de la versión 3.18.1, SimplePdo::insert(), SimplePdo::update() y SimplePdo::delete() construyen sentencias SQL concatenando el argumento $table y las claves del array $data directamente en la consulta, sin comillas de identificador y sin validación. Cuando una aplicación reenvía formas de datos controladas por el usuario a estas funciones auxiliares - un patrón común y documentado, p. ej. $db  ->  insert(’users’, $request  ->  data  ->  getData()) - un atacante puede inyectar SQL arbitrario creando claves de array maliciosas. Esta vulnerabilidad está corregida en la versión 3.18.1."
