CVE-2024-8062

A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a `HEAD` request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests.

Summary		(es) Una vulnerabilidad en el endpoint de escritura anticipada de h2oai/h2o-3 versión 3.46.0 permite una denegación de servicio. El endpoint ejecuta una solicitud `HEAD` para verificar la existencia de un recurso específico sin establecer un tiempo de espera. Un atacante puede explotar esto enviando múltiples solicitudes a un servidor controlado por él que se bloquea, lo que provoca el bloqueo de la aplicación y la incapacidad de responder a otras solicitudes.
