Descriptions

Elasticsearch versions 7.7.0 to 7.10.1 contain an information disclosure flaw in the async search API. Users who execute an async search will improperly store the HTTP headers. An Elasticsearch user with the ability to read the .tasks index could obtain sensitive request headers of other users in the cluster. This issue is fixed in Elasticsearch 7.10.2

Elasticsearch versiones 7.7.0 hasta 7.10.1, contienen un fallo de divulgación de información en la API de búsqueda asíncrona. Los usuarios que ejecutan una búsqueda asíncrona almacenarán inapropiadamente los encabezados HTTP. Un usuario de Elasticsearch con la capacidad de leer el índice .tasks podría obtener encabezados de petición confidenciales de otros usuarios en el clúster. Este problema es corregido en Elasticsearch versión 7.10.2
