A flaw was found in Traefik's HTTP/2 request handling. A remote attacker can exploit this vulnerability by rapidly creating and canceling HTTP/2 streams. This can exhaust server resources, leading to a denial of service (DoS) and making the service unavailable to legitimate users. This issue is inherited from the Go standard library's HTTP/2 implementation, known as the 'Rapid Reset' technique.
