Undertow: undertow madeyoureset http/2 ddos vulnerability_CVE-2025-9784

{
    "lastseen": "",
    "description": "A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the \"MadeYouReset\" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).",
