RabbitMQ 4.1.x < 4.1.11 / 4.2.x < 4.2.9 / 4.3.x < 4.3.3 Super Stream Binding Keys Denial of Service

high Nessus Plugin ID 362551

Synopsis

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

Description

The version of RabbitMQ installed on the remote host is 4.1.x prior to 4.1.11, or 4.2.x prior to 4.2.9, or 4.3.x prior to 4.3.3. It is, therefore, affected by a denial of service vulnerability:

- The stream management HTTP API handler for super stream creation (PUT /api/stream/super-streams/{vhost}/{name}) builds the full list of streams from the client-supplied binding-keys field before it checks the user's resource permissions. An authenticated management user with access to the vhost, but with no configure, write, or read permission, can therefore force large memory allocations and crash a node that runs under a memory limit.
(CVE-2026-67408)

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

Solution

Upgrade to RabbitMQ version 4.1.11, 4.2.9, 4.3.3, or later.
