DescriptionGitHub Advisory

Dataease is an open source data visualization analysis tool. In DataEase 2.10.19 and earlier, the static resource upload interface allows SVG uploads. However, backend validation only checks whether the XML is parseable and whether the root node is svg. It does not sanitize active content such as onload/onerror event handlers or script-capable attributes. As a result, an attacker can upload a malicious SVG and then trigger script execution in a browser by visiting the exposed static resource URL, forming a full stored XSS exploitation chain. This vulnerability is fixed in 2.10.20.

AnalysisAI

Stored XSS in Dataease 2.10.19 and earlier allows authenticated users to upload malicious SVG files that bypass backend validation by lacking proper sanitization of event handlers and script-capable attributes. An attacker can exploit this vulnerability to execute arbitrary JavaScript in victims' browsers when they access the uploaded static resource, achieving persistent code execution. …
