RabbitMQ < 4.2.6 Stream Protocol Frame Size DoS

high Nessus Plugin ID 327578

Synopsis

The RabbitMQ installed on the remote host is affected by a vulnerability.

Description

The version of RabbitMQ installed on the remote host is affected by a denial of service vulnerability:

 - The RabbitMQ stream listener does not enforce the configured stream frame-size limit while assembling frames during authentication and before Tune negotiation, allowing an unauthenticated remote client to declare oversized frame lengths and consume broker memory in rabbit_stream_core. (CVE-2026-57220)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to RabbitMQ version 4.2.6 or later.
