Qix maintainer's npm account was phished and used to publish malicious versions of widely used packages (including `debug` and multiple packages in the `chalk` ecosystem). The injected code appears designed to execute in the browser, hooking web APIs to silently rewrite cryptocurrency addresses and wallet interactions, while being largely inert in pure Node.js/server contexts.
SQL read-only bypass vulnerabilities present significant security risks and have been shown to impact real-world MCP servers such as those from Anthropic, and other various open-source MCP server implementations. This article explores the nature of these vulnerabilities, how attackers exploit them, and best practices to mitigate such risks. By understanding the mechanisms and implementing robust security measures, developers can safeguard their MCP servers against these threats.
This guide focuses on securing the MCP Server against command injection vulnerabilities by replacing the unsafe exec function with execFile. By the end of this tutorial, you'll have a more secure MCP Server implementation, reducing the risk of malicious command execution.
A security disclosure details an Argument Injection vulnerability in the `ggit` npm package version `2.4.12` and earlier. Let's break down the issue and how to address it.
A critical access control vulnerability in the Simple PSQL MCP Server allows attackers to bypass read-only restrictions through PostgreSQL function abuse. Learn how naive SQL filtering creates serious security risks.
A critical vulnerability in `ggit`, an npm package simplifying Git interactions through Node.js promises, exposes a command injection risk. Learn how this flaw can be exploited and best practices for secure coding.
