#xss

### Summary A XSS(cross-site scripting) vulnerability is caused by insufficient filtering of input by web applications. Attackers can leverage this XSS vulnerability to inject malicious script code (HTML code or client-side Javascript code) into web pages, and when users browse these web pages, the malicious code will be executed, and the victims may be vulnerable to various attacks such as cookie data theft, etc. ### Details 1. Send a Message `<iframe src="javascript:alert(document.cookie);">` from User in a chat box: <img width="1396" alt="image" src="https://github.com/user-attachments/assets/b472e304-9e7a-40d2-8469-675a5f0744e5" /> ##### Trigger in other ways: 2. Create a Agentflow in cloud platform (https://cloud.flowiseai.com/agentflows) 3. Create a Custom function as an example, use the below example code. ``` const fetch = require('node-fetch'); const url = 'https://external.website'; const options = { method: 'GET', headers: { 'Content-Type': 'application/js...

### Summary A Cross-Site Scripting (XSS) risk exists in NiceGUI when developers render unescaped user input into the DOM using `ui.html()`. Before version 3.0, NiceGUI does not enforce HTML or JavaScript sanitization, so applications that directly combine components like `ui.input()` with `ui.html()` without escaping may allow attackers to execute arbitrary JavaScript in the user’s browser. Same holds for `ui.chat_message` with HTML content. Applications that directly reflect user input via `ui.html()` (or `ui.chat_message` in HTML mode) are affected. This may lead to client-side code execution (e.g., session hijacking or phishing). Applications that do not pass untrusted input into ui.html() are not affected. ### Details NiceGUI allows developers to bind user input directly into the DOM using `ui.html()` or `ui.chat_message()`. However, the library does not enforce any HTML or JavaScript sanitization, which potentially creates a dangerous attack surface for developers unaware of t...

File upload vulnerability in Fiora chat application 1.0.0 through user avatar upload functionality. The application fails to validate SVG file content, allowing malicious SVG files with embedded foreignObject elements containing iframe tags and JavaScript event handlers (onmouseover) to be uploaded and stored. When rendered, these SVG files execute arbitrary JavaScript, enabling attackers to steal user sessions, cookies, and perform unauthorized actions in the context of users viewing affected profiles.

Cross Site Scripting (XSS) vulnerability in Fiora chat application 1.0.0 allows arbitrary JavaScript execution when malicious SVG files are rendered by other users.
