CVE-2026-57211: CWE-36: Absolute Path Traversal in rabbitmq rabbitmq-server
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.
AI Analysis
Technical Summary
RabbitMQ-server versions before 4.1.11 and 4.2.6 on Windows contain an absolute path traversal vulnerability in the management plugin's static file handler (rabbit_mgmt_wm_static). When multiple management extension plugins are enabled, the handler passes URL-encoded backslashes to erl_prim_loader:read_file_info without proper path validation. This flaw can cause the server to make outbound DNS and SMB requests to attacker-controlled UNC paths, potentially exposing sensitive information or enabling further attacks. The issue is resolved in versions 4.1.11 and 4.2.6.
Potential Impact
An attacker can exploit this vulnerability to cause the RabbitMQ server to initiate outbound DNS and SMB requests to attacker-controlled UNC paths. This can lead to information disclosure or facilitate further attacks via network interactions. The CVSS score of 6.5 reflects a medium severity with high confidentiality impact, low integrity impact, and no availability impact.
Mitigation Recommendations
This vulnerability is fixed in RabbitMQ versions 4.1.11 and 4.2.6. Users should upgrade to at least one of these versions to remediate the issue. No official temporary fixes or workarounds are provided in the available data. Patch status is not explicitly confirmed in a vendor advisory; therefore, verify with the vendor for the latest remediation guidance.
