El endpoint vulnerable expone estad\u00edsticas detalladas sobre conexiones activas, junto con la capacidad de modificar el nivel de registro de conexiones proxy sin requerir credenciales de autenticaci\u00f3n adecuadas. Este problema afecta a las versiones de Apache Pulsar de 2.6.0 a 2.10.5, de 2.11.0 a 2.11.2, de 3.0.0 a 3.0.1 y 3.1.0. Los riesgos conocidos incluyen la exposici\u00f3n de informaci\u00f3n confidencial, como la IP del cliente conectado, y la manipulaci\u00f3n no autorizada del nivel de registro, lo que podr\u00eda conducir a una condici\u00f3n de denegaci\u00f3n de servicio al aumentar significativamente la sobrecarga de registro del proxy.
