Descripción

*** Pendiente de traducción *** Uncontrolled recursion in the unknown-key skip path of the aws-smithy-json runtime crate before 0.62.7, which the smithy-rs code generator invokes from every generated struct deserializer, might allow remote unauthenticated users to cause a denial of service (process abort via stack exhaustion) via a single small HTTP request containing deeply nested JSON to a smithy-rs generated server.<br /> <br /> <br /> <br /> To remediate this issue, users should upgrade to aws-smithy-json 0.62.7 or later and rebuild.
