0 CVE-2026-21873 is a high-severity cross-site scripting (XSS) vulnerability in the Python UI framework NiceGUI versions 2.22.0 through 3.4.1. The flaw arises from unsafe handling of the URL fragment identifier in the pushstate event listener used by ui.sub_pages, allowing attackers to manipulate the URL fragment via cross-site iframes without requiring user interaction or privileges. This can lead to partial compromise of confidentiality and integrity by injecting malicious scripts. The vulnerability has been patched in version 3.5.
