+# Security Policy
+## Supported Versions
+Security updates are applied only to the latest release.
+## Reporting a Vulnerability
+If you have discovered a security vulnerability in this project, please report it privately. **Do not disclose it as a public issue.** This gives us time to work with you to fix the issue before public exposure, reducing the chance that the exploit will be used before a patch is released.
+Please disclose it at [security advisory](https://github.com/godbus/dbus/security/advisories/new).
+This project is maintained by a team of volunteers on a reasonable-effort basis. As such, vulnerabilities will be disclosed in a best effort base.
