Prior to versions 3.31.0, 3.27.2, and 3.20.5, a vulnerability exists in the HTTP layer of Quarkus REST related to response handling. When a response is being written, the framework waits for previously written response chunks to be fully transmitted before proceeding. If the client connection is dropped during this waiting period, the associated worker thread is never released and becomes permanently blocked. Under sustained or repeated occurrences, this can exhaust the available worker threads, leading to degraded performance, or complete unavailability of the application. This issue has been patched in versions 3.31.0, 3.27.2, and 3.20.5. A workaround involves implementing a health check that monitors the status and saturation of the worker thread pool to detect abnormal thread retention early."}, {"lang": "es", "value": "Quarkus es un framework Cloud Native, (Linux) Contenedor First para escribir aplicaciones Java. Antes de las versiones 3.31.0, 3.27.2 y 3.20.5, existe una vulnerabilidad en la capa HTTP de Quarkus REST relacionada con el manejo de respuestas. Cuando se est\u00e1 escribiendo una respuesta, el framework espera a que los fragmentos de respuesta escritos previamente se transmitan completamente antes de continuar. Si la conexi\u00f3n del cliente se cae durante este per\u00edodo de espera, el hilo de trabajador asociado nunca se libera y queda permanentemente bloqueado. Bajo ocurrencias sostenidas o repetidas, esto puede agotar los hilos de trabajador disponibles, lo que lleva a un rendimiento degradado o a la indisponibilidad completa de la aplicaci\u00f3n. Este problema ha sido parcheado en las versiones 3.31.0, 3.27.2 y 3.20.5.
