CVE-2026-78663 is a vulnerability in the Go standard library net/http package involving HTTP/2 server flow control. The server can incorrectly refund connection-level flow control credits twice for the same data when a client resets a stream and when the request handler reads buffered data. This allows a malicious client to bypass the configured connection-level flow control limit (MaxReceiveBufferPerConnection), although total buffered data remains constrained by other limits.
