It is simple to exploit because it does not require authentication and could result in a Denial of Service (DoS). While some DoS flaws are classified as Moderate, \u201cMadeYouReset\u201d is Important because of the limited barriers (no specialized tooling or advanced scripting) to exploitation which directly impacts service availability. The vulnerability arises from an implementation weakness in HTTP/2 stream reset handling \u2014 malformed client requests can trigger server-side resets without incrementing abuse counters, allowing an attacker to bypass built-in request throttling and overhead limits. Since these resets consume CPU and memory resources and can be generated at scale over a single TCP/TLS connection, a remote attacker could exhaust server capacity quickly, impacting all legitimate clients.", "threat_severity": "Important"}
