Official Description

RabbitMQ is a messaging and streaming broker. Prior to 4.1.11 and 4.2.6 on Windows, the RabbitMQ management plugin static file handler rabbit_mgmt_wm_static can pass URL-encoded backslashes to erl_prim_loader:read_file_info before path validation when multiple management extension plugins are enabled, causing outbound DNS and SMB requests to attacker-controlled UNC paths. This issue is fixed in versions 4.1.11 and 4.2.6.

Risk Analysis

This critical vulnerability in RabbitMQ's management plugin on Windows allows an unauthenticated attacker to trigger outbound DNS and SMB requests to attacker-controlled UNC paths. This can lead to information disclosure or potentially further attacks. With a CVSS score of 10.0, this is an extremely severe vulnerability.

No public exploit is currently known for this vulnerability. It is remotely exploitable due to its network attack vector and low attack complexity.

Recommended Action

Users should upgrade RabbitMQ to versions 4.1.11 or 4.2.6 or later on Windows. Restrict outbound network traffic from RabbitMQ servers to only necessary destinations.

Technical Analysis

CVE-2026-57211 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
