CVE-2026-16756
7.5
HIGH
Vulnerability Description
Missing connection and header-read timeouts and the absence of a concurrent-connection cap in the default serve() path of Amazon aws-smithy-http-server might allow remote attackers to cause a denial of service by opening many connections and sending partial requests that are never completed, exhausting server sockets and tasks.
To mitigate this issue, users should upgrade to aws-smithy-http-server 0.66.5 or later.
