CVE-2026-66077 is a cross-site scripting (XSS) vulnerability in RabbitMQ's management UI prior to versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6. The issue arises because the management UI uses EJS 1.0 templating which does not HTML-escape certain certificate subject fields. An attacker who can obtain a TLS client certificate signed by a trusted CA and with a crafted Subject DN can inject JavaScript that executes in the administrator's browser when viewing connection details. This allows full account takeover capabilities via the management UI. The vulnerability requires the TLS listener to be configured with verify_peer enabled and the attacker to have a CA-signed client certificate. A fix is available in the stated versions.
