+
+I'm happy to announce the release of ReactJS.NET 1.5.1! This is a bug fix release and fixes a potential XSS issue with server-side rendering. JSON.NET does not escape HTML characters in its JSON output by default. As ReactJS.NET uses JSON.NET to output the props of server-side rendered components, a prop that accepts arbitrary user input could potentially contain script tags, allowing for XSS.
+
+Escaping of HTML is now enabled by default. If you are using custom JSON serializer settings, you can enable HTML escaping by setting `StringEscapeHandling` to `StringEscapeHandling.EscapeHtml`:
+
+```csharp
+ReactSiteConfiguration.Configuration.SetJsonSerializerSettings(
+  new JsonSerializerSettings
+  {
+    StringEscapeHandling = StringEscapeHandling.EscapeHtml
+  }
+);
+```
+
+Have fun, and as always, please feel free to send feedback or bug reports
+[on GitHub](https://github.com/reactjs/React.NET).
