PYSEC-2026-95
NiceGUI is a Python-based UI framework. Prior to 3.7.0, NiceGUI's FileUpload.name property exposes client-supplied filename metadata without sanitization, enabling path traversal when developers use the pattern UPLOAD_DIR / file.name. Malicious filenames containing ../ sequences allow attackers to write files outside intended directories, with potential for remote code execution through application file overwrites in vulnerable deployment patterns. This design creates a prevalent security footgun affecting applications following common community patterns. Note: Exploitation requires application code incorporating file.name into filesystem paths without sanitization. Applications using fixed paths, generated filenames, or explicit sanitization are not affected. This vulnerability is fixed in 3.7.0.

VCID-3hyc-h7ym-y7c9 NiceGUI Stored/Reflected XSS in ui.interactive_image via unsanitized SVG content A Cross-Site Scripting (XSS) vulnerability exists in the `ui.interactive_image` component of NiceGUI (v3.3.1 and earlier). The component renders SVG content using Vue's `v-html` directive without any sanitization. This allows attackers to inject malicious HTML or JavaScript via the SVG `<foreignObject>` tag.

VCID-4btp-8pnj-rbgj NiceGUI has a path traversal in app.add_media_files() allows arbitrary file read A directory traversal vulnerability in NiceGUI's `App.add_media_files()` allows a remote attacker to read arbitrary files on the server filesystem. CVE-2025-66645
GHSA-hxp3-63hc-5366
VCID-dgqv-w1gf-qqby NiceGUI Reflected XSS in ui.add_css, ui.add_scss, and ui.add_sass via Style Injection A Cross-Site Scripting (XSS) vulnerability exists in `ui.add_css`, `ui.add_scss`, and `ui.add_sass` functions in NiceGUI (v3.3.1 and earlier). These functions allow developers to inject styles dynamically. However, they lack proper sanitization or encoding for the JavaScript context they generate. An attacker can break out of the intended `<style>` or `<script>` tags by injecting closing tags (e.g., `</style>` or `</script>`), allowing for the execution of arbitrary JavaScript. CVE-2025-66469
