Description
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up.
This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
Mitigation
Minimal update. May introduce new vulnerabilities or breaking changes.
