description

Langflow releases before the fixed versions allow MCP server configuration to invoke operating-system commands on the Langflow host. An attacker who can manage MCP servers or create relevant flows can execute commands as the Langflow service account; an exposed instance with automatic login enabled may be reachable without an account.

mitigation

Upgrade langflow and lfx to 1.10.3 or later, and langflow-base to 0.10.3 or later. Disable LANGFLOW_AUTO_LOGIN and limit access to MCP settings and flow creation.

fixed in 1.10.3, 0.10.3
