A debug error message vulnerability allows an attacker to obtain sensitive information about the underlying system, potentially compromising its security. WebSocket connections can return debug messages that reveal internal details, making it essential to disable these messages in production environments.


To mitigate this risk, ensure debugging is disabled or configure the server to only display minimal debug messages during production. This can be achieved by modifying configuration files or setting environment variables.
