CVE-2026-57211
Last modified
CVE-2026-57211 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
