CVE-2026-77410

High

Description

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, Channel.recvContent in channel.go preallocates the message body slice with the uint64 ch.header.Size value supplied by an AMQP content header without capping the allocation to the negotiated Connection.Config.FrameSize value. A malicious or compromised broker can send an extreme declared body size and cause the Go runtime to attempt a correspondingly large allocation before body data is received. The allocation can exhaust memory and terminate the client process. This issue is fixed in version 1.13.0.
