+# Reporting a security vulnerability
+You can report a security vulnerability through Discord or through email.
+
+If you want to send an email, you can contact us at <[email protected]>.
+If you want to contact us through Discord, you can join [our server](https://discord.gg/MwDDf6t)
+and then **privately** message anyone with the `@Wizard` or `@SS14 Maintainer` role.
+
+In either case, **do not publicly disclose the vulnerability until we explicitly give
+you permission to do so**.
