Affected: zauberzeug nicegui

NiceGUI is a Python-based UI framework. Versions 3.3.1 and below are subject to a XSS vulnerability through the ui.interactive_image component of NiceGUI. 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 whenever the image component is rendered or updated. This is particularly dangerous for dashboards or multi-user applications displaying user-generated content or annotations. This issue is fixed in version 3.4.0.

 https://cve.radiocsirt.org/vuln/pysec-2026-1696 PYSEC-2026-1696 — NiceGUI Stored/Reflected XSS in ui.interactive_image via unsanitized SVG content 2026-10-06T19:18:22.410849+00:00

Affected: PyPI: nicegui

### Summary 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.

### Details The vulnerability is located in `nicegui/elements/interactive_image.js`. The component uses the following code to render content: ```javascript <g v-html="content"></g> ``` Vue's v-html directive renders raw HTML strings into the DOM. If an application allows user-controlled input to be passed to the content property of an interactive image, an attacker can embed a <foreignObject> tag containing malicious scripts, bypassing typical image restrictions.

### PoC ```python from nicegui import ui

@ui.page('/') def main(): ui.label('NiceGUI SVG XSS PoC') # Standard image loading img = ui.interactive_image('[https://picsum.photos/640/360](https://picsum.photos/640/360)') # Payload: Embeds raw HTML execution inside SVG # This executes immediately when the image component is rendered img.content = ( '<foreignObject>' '<body xmlns="[http://www.w3.org/1999/xhtml](http://www.w3.org/1999/xhtml)">' '<img src=x onerror=alert("XSS-SVG")>' '</body>' '</foreignObject>' )

ui.run() ```

### Impact - Type: Reflected / Stored XSS (depending on data source)

- Severity: Moderate
