golang-github-rabbitmq-amqp091-go: RabbitMQ amqp091-go is a Go AMQP 0.9.1 client
CVE-2026-77403 is fixed in golang-github-rabbitmq-amqp091-go on 1 platform by DEBIAN-CVE-2026-77403 (version 1.14.0-1), released September 18, 2026. It is not reported as exploited. Patch Radar priority: Routine.
RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, Connection.openTune in connection.go accepts a server-advertised FrameMax below the AMQP frameMinSize value of 4096 bytes because the connection negotiation loop does not enforce the protocol minimum. A malicious or compromised AMQP broker can therefore advertise an extremely small FrameMax, causing later client publications to be fragmented into excessive numbers of frames and write operations. This can consume CPU and stall the client or its host. This issue is fixed in version 1.13.0.
