+
+## Changelog
+
+Compared to the latest release [3.4.4](release_notes_344.html), the following changes and bugfixes were added.
+
+### Security fixes
+
+
+#### Security fix for CVE-2024-5165
+
+The Eclipse Ditto's Web-UI, the [Explorer User Interface](https://eclipse.dev/ditto/user-interface.html), was vulnerable 
+to Cross-Site Scripting (XSS) at multiple input fields.  
+Affected versions are all Ditto-UI versions starting from when the Ditto-UI was introduced, with Ditto 
+[3.0.0](release_notes_300.html#new-ditto-explorer-ui).
+
+This is tracked through CVE [https://nvd.nist.gov/vuln/detail/CVE-2024-5165](CVE-2024-5165).
+
+The issue was detected and reported by [Manuel Sommer](https://gitlab.eclipse.org/manuelsommer) and 
+[Quirin Zießler](https://gitlab.eclipse.org/quirinziessler) and disclosed via the 
+[Eclipse Vulnerability Reporting](https://www.eclipse.org/security/) process.  
+We like to thank them for the detection and the effort of reporting the affected input fields.
+
+For any users of Eclipse Ditto who deployed also the Ditto Web-UI, we recommend updating the Web-UI.  
+If the Web-UI is not deployed, no action to update is needed, as the **Ditto backend is not affected**.
