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...

CVE-2024-21541

CVE-2024-21541 affects the npm package dom-iterator prior to version 1.0.1 . The vulnerability stems from use of the Function constructor without complete input sanitization, allowing an attacker-controlled input to generate a new function body, with risks similar to eval. This is corroborated by...

PT-2024-18954 · Unknown · Dom-Iterator

Name of the Vulnerable Software and Affected Versions: dom-iterator versions prior to 1.0.1 Description: The issue is related to Arbitrary Code Execution due to the use of the Function constructor without complete input sanitization. This allows an attacker to generate a new function body, posing...

CVE-2023-50883

ONLYOFFICE Docs before 8.0.1 allows XSS because a macro is an immediately-invoked function expression IIFE, and therefore a sandbox escape is possible by directly calling the constructor of the Function object. NOTE: this issue exists because of an incorrect fix for CVE-2021-43446...
