The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream refunding data for any sent-but-unread portion of the stream, and again when a request handler reads the buffered data. A malicious client can exploit this to bypass the configur...

CVE-2026-78663: Multiple Operations on Resource in Single-Operation Context
The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream refunding data for any sent-but-unread portion of the stream, and again when a request handler reads the buffered data. A malicious client can exploit this to bypass the configur...
Denial-of-service (DoS)
org.apache.qpid, protonj2 is vulnerable to a denial-of-service DoS. The vulnerability is due to improper handling of the session flow-control incoming window, which allows an authenticated attacker to exceed the allowed window and potentially exhaust resources...
Astra Linux – Vulnerability in Node.js
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE 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 vulnerabili...
The vulnerability of the Locale() function in the modules/web/middleware/locale.go file of the Git repository management system Gitea allows a hacker to trigger a service failure.
The vulnerability of the Locale function in the modules/web/middleware/locale.go file of the Git repository management system Gitea is related to the improper implementation of flow control. Exploiting this vulnerability could allow a malicious actor to cause service failures...
Uncontrolled Resource Consumption
Apache Qpid Broker-J is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to improper enforcement of the session flow control incoming window, which allows an authenticated attacker to exceed the permitted window and cause resource exhaustion, potentially resulting in a...

The Rocky Linux 9.6 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1776939108 advisory. - A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE frames on stream 0 connection-level that cause the flow...
openssl: OpenSSL: Denial of Service via unenforced QUIC connection flow control
A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS due to missing connection-level flow control enforcement in the QUIC protocol implementation. By opening multiple streams that respect individual stream limits while preventing data consumption, the attacker can forc...

Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the QUIC flow control enforcement, which applies the stream level window but not the connection level one. An attacker can force roughly 100 MB of allocation against a default 768 ...
