Existe una vulnerabilidad en las versiones 2.0 a 8.0 en la funci\u00f3n Lector de Registros de este complemento. Un archivo de registro creado con fines maliciosos puede conducir a la ejecuci\u00f3n de c\u00f3digo arbitrario cuando un usuario lo lee con comandos del lector de registros. El comando de lectura de registros procesa las entradas de registro de voz de manera insegura. Las expresiones de Python incrustadas en el registro pueden ser evaluadas cuando las entradas de voz son le\u00eddas con comandos de lectura de registros. Un atacante puede explotar esto convenciendo a un usuario de abrir un archivo de registro creado con fines maliciosos y de analizarlo usando los comandos de lectura de registros. Cuando se lee el registro, el c\u00f3digo controlado por el atacante puede ejecutarse con los privilegios del usuario actual.\nEste problema no requiere privilegios elevados y se basa \u00fanicamente en la interacci\u00f3n del usuario (abrir el archivo de registro). La versi\u00f3n 9.0 contiene una correcci\u00f3n para el problema. Como soluci\u00f3n alternativa, evite usar los comandos de lectura de registros, o al menos, los comandos para moverse al mensaje de registro siguiente/anterior (cualquier mensaje o comandos para cada tipo de mensaje).
