security
Summary
IBM Langflow OSS (open-source software) versions 1.0.0 through 1.10.0 have a vulnerability that allows remote code execution (running malicious commands on a system from a distance) because the software doesn't properly validate MCP server configuration files (text files that tell the system how to connect to external services). This is a serious security flaw because an attacker could exploit incomplete validation enforcement to execute unauthorized code.
