      "value": "Self Cross-Site Scripting (Self-XSS) vulnerability in the RD Station Conversas chat feature. The vulnerability lies in the ‘name’ parameter of the initialisation process due to incorrect sanitisation of user-supplied input. Exploitation allows specially crafted JavaScript code to be injected, which is executed within the context of the user’s own session who provides the payload. The demonstrated impact is limited to the user who enters and executes the payload."

      "value": "Vulnerabilidad de Cross-Site Scripting (XSS) almacenado en el chat de RD Station Conversas. La vulnerabilidad reside en el parámetro ’name’ del proceso de inicialización debido a una sanitización inadecuada de la entrada del usuario. La vulnerabilidad no se limita a la autoexplotación: cuando un agente de soporte se une a la conversación, el script malicioso también se ejecuta en su navegador, aumentando el impacto. La explotación exitosa de esta vulnerabilidad podría permitir a un atacante ejecutar código JavaScript arbitrario dentro del contexto de la aplicación."
