The post ‘By Design’ Flaw in MCP Could Enable Widespread AI Supply Chain Attacks appeared first on SecurityWeek.","Researchers at OX Security discovered a critical architectural flaw in Anthropic's Model Context Protocol (MCP) that allows arbitrary commands to execute silently without sanitization, potentially compromising millions of downstream users. The flaw affects STDIO MCP servers across enterprises using agentic AI, and despite coordinated disclosure efforts, Anthropic has declined to fix the underlying design issue, instead recommending cautious use. OX warns this could enable widespread data theft, API key exposure, malware installation, and system takeover across the AI supply chain.","Architectural flaw in Anthropic's MCP allows unsanitized
