CVE-2025-55346

Flowise exposes a remote code execution vector via the CustomMCP tool: input from mcpServerConfig is passed into a dynamic Function constructor (Function('return '+ input)()) in the host context, which can access global process and Node.js modules. This allows arbitrary JS execution (RCE) when cr...

Flowise 安全漏洞

Flowise is a FlowiseAI open source tool for easily building LLM applications. A security vulnerability exists in Flowise that stems from user-controlled input flow to an insecure dynamic function constructor implementation that could lead to the execution of arbitrary non-sandboxed JS code in the...

Malicious code in ts-runtime-compat-check (npm)

The npm package ts-runtime-compat-check is a malicious package that functions as a key component in a remote code execution attack chain. This package: 1. Contains a postinstall script that executes lib/install.js 2. The install script makes HTTP requests to a server specified by an environment...

dom-iterator code execution vulnerability

Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not...
