### Summary User-controlled input flows to an unsafe implementaion of a dynamic Function constructor , allowing a malicious actor to run JS code in the context of the host (not sandboxed) leading to RCE. ### Details When creating a new `Custom MCP` Chatflow in the platform, the MCP Server Config displays a placeholder hinting at an example of the expected input structure: ```json { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/files"] } ``` Behind the scene, a `POST` request to `/api/v1/node-load-method/customMCP` is sent with the provided MCP Server Config, with additional parameters (excluded for brevity): ```json { ...SNIP... "inputs":{ "mcpServerConfig":{ "command":"npx", "args":[ "-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/files" ] } }, "loadMethod":"listActions" ...SNIP... } ``` Sending the same request with the para...

Passwork is positioned as an on-premises unified platform for both password and secrets management, aiming to address the increasing complexity of credential storage and sharing in modern organizations. The platform recently received a major update that reworks all the core mechanics. Passwork 7 introduces significant changes to how credentials are organized, accessed, and managed, reflecting

Cybersecurity never stops—and neither do hackers. While you wrapped up last week, new attacks were already underway. From hidden software bugs to massive DDoS attacks and new ransomware tricks, this week’s roundup gives you the biggest security moves to know. Whether you’re protecting key systems or locking down cloud apps, these are the updates you need before making your next security

Darktrace researchers have uncovered ShadowV2, a new botnet that operates as a DDoS-for-hire service by infecting misconfigured Docker containers on AWS cloud servers.

Cybersecurity researchers have disclosed two security flaws in Wondershare RepairIt that exposed private user data and potentially exposed the system to artificial intelligence (AI) model tampering and supply chain risks. The critical-rated vulnerabilities in question, discovered by Trend Micro, are listed below - CVE-2025-10643 (CVSS score: 9.1) - An authentication bypass vulnerability that

Fake software—including Malwarebytes and LastPass—is currently circulating on GitHub pages, in a large-scale campaign targeting Mac users.

The for-hire platform leverages legitimate cloud-native tools to make detection and disruption harder for defenders and SOC analysts.

Cybersecurity researchers have disclosed details of a new botnet that customers can rent access to conduct distributed denial-of-service (DDoS) attacks against targets of interest. The ShadowV2 botnet, according to Darktrace, predominantly targets misconfigured Docker containers on Amazon Web Services (AWS) cloud servers to deploy a Go-based malware that turns infected systems into attack nodes

### 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...
