Summary
IBM Langflow OSS (an open-source AI workflow tool) versions 1.0.0 through 1.10.3 has a vulnerability where attackers who are already logged in can run arbitrary commands on the server due to improper validation of the command field in MCP (model context protocol, a system for connecting AI models to external tools) server configurations. This is an example of OS command injection (CWE-78), where special characters meant for system commands aren't properly filtered.
