CVE-2026-27156 NiceGUI has XSS via Code Injection

NiceGUI is a Python-based UI framework. Prior to version 3.8.0, several NiceGUI APIs that execute methods on client-side elements Element.runmethod, AgGrid.rungridmethod, EChart.runchartmethod, and others use an eval fallback in the JavaScript-side runMethod function. When user-controlled input i...

CVE-2026-27156

NiceGUI (Python) before version 3.8.0 is vulnerable to XSS via code injection in client-side runMethod-related APIs (Element.run_method, AgGrid.run_grid_method, EChart.run_chart_method, etc.) due to eval fallback and unsafe string interpolation of method names. The issue allows attacker-controlle...

NiceGUI 跨站脚本漏洞

NiceGUI is an easy-to-use, Python-based UI framework developed under the open source license. Versions of NiceGUI prior to 3.8.0 contained a cross-site scripting vulnerability. This vulnerability stemmed from the use of eval in multiple client APIs, and incorrect escaping of method names, which...
