CVE-2026-49867: Dataease

Medium severity, CVSS 6.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
