CVE-2026-57211: CWE-36: Absolute Path Traversal in rabbitmq rabbitmq-server
CVE-2026-57211 is an absolute path traversal vulnerability in the RabbitMQ management plugin static file handler on Windows. It affects versions prior to 4.1.11 and 4.2.6 when multiple management extension plugins are enabled. The vulnerability allows URL-encoded backslashes to bypass path validation, causing outbound DNS and SMB requests to attacker-controlled UNC paths. This can lead to information disclosure. The issue is fixed in RabbitMQ versions 4.1.11 and 4.2.6.
AI Analysis
Technical Summary
This vulnerability in rabbitmq-server affects the management plugin static file handler (rabbit_mgmt_wm_static) on Windows platforms. When multiple management extension plugins are enabled, the handler can pass URL-encoded backslashes to erl_prim_loader:read_file_info without proper path validation. This allows an attacker to cause the server to make outbound DNS and SMB requests to attacker-controlled UNC paths, potentially leaking sensitive information. The vulnerability is addressed in versions 4.1.11 and 4.2.6.
Potential Impact
Exploitation of this vulnerability can cause the RabbitMQ server to make outbound DNS and SMB requests to attacker-controlled UNC paths. This behavior may lead to information disclosure about the internal network or system. The CVSS score of 6.5 reflects a medium severity with high confidentiality impact but low integrity and availability impact.
Mitigation Recommendations
This vulnerability is fixed in RabbitMQ versions 4.1.11 and 4.2.6. Users should upgrade to at least these versions to remediate the issue. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the vendor advisory stating the fix in these versions.
