Langflow < 1.8.2 Unauthenticated Remote Code Execution

critical Web App Scanning Plugin ID 115176

Synopsis

Langflow < 1.8.2 Unauthenticated Remote Code Execution

Description

Langflow versions before 1.8.2 allow unauthenticated remote code execution via the '/api/v1/build_public_tmp/{flow_id}/flow' endpoint. Attacker-supplied flow data with arbitrary Python code in node definitions is passed to exec() without sandboxing, enabling code execution without authentication. This detection is included in the AI and LLM category.

Solution

Upgrade to Langflow version 1.8.2 or later.
