GeoServer is an open source server that allows users to share and edit geospatial data. org.geowebcache.GeoWebCacheDispatcher.handleFrontPage(HttpServletRequest, HttpServletResponse) has no check to hide potentially sensitive information from users except for a hidden system property to hide the storage locations that defaults to showing the locations. This vulnerability is fixed in 2.26.2 and 2.25.6.
