Apple on Monday backported fixes for a recently patched security flaw that has been actively exploited in the wild. The vulnerability in question is CVE-2025-43300 (CVSS score: 8.8), an out-of-bounds write issue in the ImageIO component that could result in memory corruption when processing a malicious image file. "Apple is aware of a report that this issue may have been exploited in an

### Summary The Custom MCPs feature is designed to execute OS commands, for instance, using tools like `npx` to spin up local MCP Servers. However, Flowise's inherent authentication and authorization model is minimal and lacks role-based access controls (RBAC). Furthermore, the default installation of Flowise operates without authentication unless explicitly configured using the `FLOWISE_USERNAME` and `FLOWISE_PASSWORD` environment variables. This combination presents a significant security risk, potentially allowing users on the platform to execute unsandboxed system commands. This can result in Remote Code Execution (RCE) and complete compromise of the running platform container or server. ### PoC 1. Follow the provided instructions for running the app using Docker Compose (or other methods of your choosing such as `npx`, `pnpm`, etc): https://github.com/FlowiseAI/Flowise?tab=readme-ov-file#-docker 2. Create a new file named `payload.json` somewhere in your machine, with the fo...

### Summary Missing chat flow id validation allows an attacker to access arbitrary file. ### Details Commit https://github.com/FlowiseAI/Flowise/commit/8bd3de41533de78e4ef6c980e5704a1f9cb7ae6f and https://github.com/FlowiseAI/Flowise/commit/c2b830f279e454e8b758da441016b2234f220ac7 added check for `filename` when handling file upload operations to prevent path traversal, and additional validation of `chatflowId` and `chatId` from route `/api/v1/attachments`. In some cases, however, `chatflowId` and `chatId` are not validated to ensure they are UUIDs or numbers, which may lead to security issues. **Case 1** When creating new chatflow via `/api/v1/chatflows`, function `addBase64FilesToStorage` is called if there exists base64 file data. Although the `filename` is sanitized, the `chatflowid` comes from request body directly without any validation. An attacker could exploit the path traversal here to write arbitrary file with controlled data. ```typescript export const addBase64Files...

## Description ### Cause of the Vulnerability The `CustomMCP` node allows users to input configuration settings for connecting to an external MCP (Model Context Protocol) server. This node parses the user-provided `mcpServerConfig` string to build the MCP server configuration. However, during this process, it executes JavaScript code without any security validation. Specifically, inside the `convertToValidJSONString` function, user input is directly passed to the `Function()` constructor, which evaluates and executes the input as JavaScript code. Since this runs with full Node.js runtime privileges, it can access dangerous modules such as `child_process` and `fs`. ### Vulnerability Flow 1. **User Input Received**: Input is provided via the API endpoint `/api/v1/node-load-method/customMCP` through the `mcpServerConfig` parameter. 2. **Variable Substitution**: The `substituteVariablesInString` function replaces template variables like `$vars.xxx`, but no security filtering is applie...

## Summary An authenticated admin user of **FlowiseAI** can exploit the **Supabase RPC Filter** component to execute **arbitrary server-side code** without restriction. By injecting a malicious payload into the filter expression field, the attacker can directly trigger JavaScript's `execSync()` to launch reverse shells, access environment secrets, or perform any OS-level command execution. This results in **full server compromise** and severe breach of trust boundaries between frontend input and backend execution logic. ## Details FlowiseAI includes a component called `Supabase.ts`, located at: `packages/components/nodes/vectorstores/Supabase/Supabase.ts#L237` <img width="622" height="177" alt="image(3)" src="https://github.com/user-attachments/assets/f30ccd12-4709-44ac-a6ef-8f57a1cb5c3b" /> This creates a function from user-provided string `supabaseRPCFilter` with no filtering, escaping, or sandboxing in place. Any injected JavaScript in this string is compiled and executed **im...

In a world where threats are persistent, the modern CISO’s real job isn't just to secure technology—it's to preserve institutional trust and ensure business continuity. This week, we saw a clear pattern: adversaries are targeting the complex relationships that hold businesses together, from supply chains to strategic partnerships. With new regulations and the rise of AI-driven attacks, the
