CVE-2026-57211
Description
A flaw was found in RabbitMQ. The RabbitMQ management plugin static file handler, rabbit_mgmt_wm_static, on Windows can be exploited when multiple management extension plugins are enabled. An attacker can pass specially crafted URL-encoded backslashes, bypassing path validation. This can lead to outbound DNS and Server Message Block (SMB) requests to attacker-controlled network paths, potentially disclosing sensitive information.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
