net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

CVE-2026-66075

RabbitMQ versions prior to 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.1 are vulnerable to a privilege escalation issue. The /federation-links/.../restart route incorrectly uses is_authorized_monitor, which accepts the monitoring tag , while allowing the DELETE method. Because there is no per-method ...

CVE-2026-67219 RabbitMQ: Consistent-hash exchange unbounded weight

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, addbinding/3 parses the routing key as an integer weight N and computes ring positions with lists:seqNextN0, NextN0 + N - 1. validatebinding/2 only checks N = 1 , no upper bound. The resulti...

CVE-2026-67219

RabbitMQ is affected by a vulnerability where the add_binding/3 function fails to impose an upper bound on the routing key integer weight N in the consistent-hash exchange plugin. Because validate_binding/2 only ensures N >= 1 , an attacker with write permissions on a consistent-hash exchange ...
