In versions 1.5.0 and below, email properties (such as to, subject, html, text, and attachments) are not reset between sends when a single client instance is reused across multiple .send() calls. This can cause properties from a previous send to leak into a subsequent one, potentially delivering content or recipient addresses to unintended parties. Applications sending emails to different recipients in sequence — such as transactional flows like password resets or notifications — are affected. This issue has been fixed in version 1.5.1."},{"lang":"es","value":"El SDK de Node.js de Lettermint es el SDK oficial de Node.js para Lettermint. En las versiones 1.5.0 e inferiores, las propiedades del correo electrónico (como 'para', 'asunto', 'html', 'texto' y 'archivos adjuntos') no se restablecen entre envíos cuando una única instancia de cliente se reutiliza en múltiples llamadas a .send(). Esto puede provocar que las propiedades de un envío anterior se filtren en uno posterior, entregando potencialmente contenido o direcciones de destinatarios a partes no deseadas. Las aplicaciones que envían correos electrónicos a diferentes destinatarios en secuencia — como flujos transaccionales como restablecimientos de contraseña o notificaciones — se ven afectadas.
