    Langflow: SSRF in URL-taking components (protection disabled by default / warn-only, not applied to RSS, SearXNG, Web Search, Home Assistant, Glean, Docling)

    ### Summary Before **Langflow 1.10.3**, several built-in components sent server-side HTTP requests to URLs the flow author controls, with no SSRF enforcement. An authenticated user who can build or run flows could make the Langflow server reach loopback, RFC 1918 / private networks, link-local addresses and cloud metadata endpoints (for example `http://169.254.169.254/latest/meta-data/`), and in many cases read the response back through the component output. Two things combined to cause this: 1. **Protection disabled / warn-only.** The SSRF guard (`lfx/utils/ssrf_protection.py`, added in 1.7.0 by #10544) shipped with `ssrf_protection_enabl

    Langflow: OS command injection (RCE) via arbitrary command in MCP stdio server configuration

    Langflow is a tool for building and deploying AI-powered agents and workflows. Before Langflow 1.10.3, the MCP stdio transport launched whatever command / args a user put in an MCP server configuration, with no allowlist and (before 1.10.3) wrapped in bash -c "exec {command} ...". Any user able to reach the MCP server settings ("Settings → MCP Servers → Add MCP Server", POST/PATCH /api/v2/mcp/servers/{server_name}) or to build a flow with the MCP Tools component could add a "server" whose command is an arbitrary OS command (touch, rm -rf, a reverse shell, ...). The command runs on the Langflow host as the Langflow process user as soon as Lang
