A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. ### POC #### Reference No PoCs from references. #### Github - https://github.com/fkie-cad/nvd-json-data-feeds - https://github.com/rsys-fchaliss/hebe
