+# Security Policy
+
+## Supported Versions
+
+The latest patch version of the `1.x` release series is supported for security updates.
+
+## Reporting a Vulnerability
+
+PHPCSExtra is a developer tool and should generally not be used in a production (web accessible) environment.
+
+Having said that, responsible disclosure of security issues is highly appreciated.
+
+**Please do not report or discuss security vulnerabilities through public GitHub issues, discussions, or pull requests.**
+
+Issues can be reported privately to the maintainers by opening a [Security vulnerability report](https://github.com/PHPCSStandards/PHPCSExtra/security/advisories/new).
+
+### Preferences
+
+* Please provide detailed reports with reproducible steps and a clearly defined impact.
+* Include the version number of the vulnerable package in your report.
+* Fixes are most welcome.
+    A private PR can be created from the security report to work on and discuss the patch.
