Please report any cyber security vulnerabilities you discover that are not yet publicly known, if they are: high-impact vulnerabilities that may affect many users, critical national infrastructure or physical safety and could occur in software components, protocols or hardware vulnerabilities in websites or systems for big business or government agencies. Coordinating the disclosure of vulnerabilities can minimise the potential harm caused by those vulnerabilities being exploited.
