This HTTP request smuggling vulnerability occurs because SoupServer improperly handles requests that combine Transfer-Encoding: chunked and Connection: keep-alive headers. A remote, unauthenticated client can exploit this by sending specially crafted requests, causing SoupServer to fail to close the connection as required by RFC 9112. This allows the attacker to smuggle additional requests over the persistent connection, leading to unintended request processing and potential denial-of-service (DoS) conditions."}, {"lang": "es", "value": "Se encontr\u00f3 un fallo en SoupServer. Esta vulnerabilidad de contrabando de solicitudes HTTP ocurre porque SoupServer maneja incorrectamente las solicitudes que combinan los encabezados Transfer-Encoding: chunked y Connection: keep-alive. Un cliente remoto no autenticado puede explotar esto enviando solicitudes especialmente dise\u00f1adas, lo que provoca que SoupServer no cierre la conexi\u00f3n seg\u00fan lo requerido por RFC 9112. Esto permite al atacante contrabandear solicitudes adicionales a trav\u00e9s de la conexi\u00f3n persistente, lo que lleva a un procesamiento de solicitudes no intencionado y a posibles condiciones de denegaci\u00f3n de servicio (DoS)."}], "lastModified": "2026-04-15T00:35:42.020", "sourceIdentifier": "secalert@redhat.com"}
