Admin password disclosed in BrokerNotAliveException message

MEDIUM | AUGUST 20, 2026 | CVE-2026-59271

Description

When the RabbitMQ management aliveness check fails, the configured admin password is embedded in cleartext in the thrown exception message. If a CI pipeline sets RABBITMQ_TEST_ADMIN_PASSWORD to a real credential and the broker is required (RABBITMQ_SERVER_REQUIRED=true), the password is printed into test output / CI logs where anyone with log-read access can harvest it.
