Name of the Vulnerable Software and Affected Versions
Amazon MQ MCP Server (awslabs.amazon-mq-mcp-server) versions prior to 2.0.24

Improper restriction of intended endpoints in the RabbitMQ broker connection tools may allow a remote unauthenticated actor to obtain Amazon MQ for RabbitMQ broker credentials or OAuth access tokens. This is achieved via prompt injection, where tokens or credentials are sent to a crafted endpoint controlled through a broker hostname introduced in the MCP client context.
Recommendations
Upgrade to version 2.0.24.
