CVE-2026-18140

A flaw was found in aws-smithy-json. This vulnerability allows a remote, unauthenticated attacker to cause a denial of service DoS in smithy-rs generated servers. By sending a small HTTP request containing deeply nested JSON, the attacker can trigger uncontrolled recursion in the aws-smithy-json...
