MCP Servers are increasingly popular for AI-driven workflows. However, I discovered a directory traversal vulnerability in the Mastra AI Frameworks MCP Server that could expose sensitive information. This article explores the flaw, its exploitation, and mitigation strategies.
The MCP Database Server by ExecuteAutomation had a critical vulnerability that allowed SQL injection attacks, bypassing its "read-only" mode. This article explores the flaw, its exploitation, and mitigation strategies.
Security defaults in AI frameworks are crucial. I found two critical vulnerabilities in Mastra AI's templates: Improper Access Control in `template-text-to-sql` and SSRF in `template-pdf-questions`. This article explores these flaws, their exploitation, and mitigation strategies.
The Model Context Protocol (MCP) Server by Xata had a critical vulnerability that allows SQL injection attacks, bypassing its "read-only" mode. This article explores the flaw, its exploitation, and mitigation strategies.
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.
