+## Reporting a Vulnerability

+If you think you have found a security vulnerability, please **DO NOT** disclose it publicly until we’ve had a chance to fix it.
+Please don’t report security vulnerabilities using GitHub issues, instead head over to https://spring.io/security-policy and learn how to disclose them responsibly.
