CVE-2026-49867 Details
Description
DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase template static resources let authenticated users submit TemplateManageRequest.staticResource through POST /de2api/templateManage/save or DataVisualizationServer.decompression, after which StaticResourceServer.saveFilesToServe and StaticResourceServer.saveSingleFileToServe write Base64-decoded .svg content to /de2api/static-resource/<name>.svg without validating extension, MIME type, decoded bytes, or SVG scriptability, causing stored same-origin cross-site scripting when a victim loads the resource. This issue is fixed in version 2.10.23.
A stored cross-site scripting vulnerability has been identified in DataEase versions prior to 2.10.23. This issue allows authenticated users to upload SVG files containing scripts as template static resources. The uploaded files are saved without proper validation to a publicly accessible directory, where they can execute JavaScript in the context of the DataEase application. The vulnerability arises because the static resource upload bypasses normal image validation, leaving room for exploitation when the SVG files are accessed.
Users are advised to upgrade to DataEase version 2.10.23, where this vulnerability has been fixed.
