CVE-2026-21872

Exploit

NiceGUI apps are vulnerable to XSS which uses `ui.sub_pages` and render arbitrary user-provided links

NiceGUI is a Python-based UI framework. From versions 2.22.0 to 3.4.1, an unsafe implementation in the click event listener used by ui.sub_pages, combined with attacker-controlled link rendering on the page, causes XSS when the user actively clicks on the link. This issue has been patched in version 3.5.0.
