Attack-Flow Graph

Executive Summary

This vulnerability in IBM Langflow OSS 1.0.0 through 1.10.1 allows an authenticated user to execute arbitrary commands with elevated privileges due to improper validation of user input in the Python Interpreter component.

Detection Guidance

Check Langflow version with: pip show langflow. If installed version is between 1.0.0 and 1.10.1, the system is vulnerable. Inspect API endpoints for unauthenticated access or improper authorization. Monitor for unusual command execution patterns or unauthorized file access in logs.

Impact Analysis

An attacker could exploit this to gain control over the system, execute malicious commands, access sensitive data, disrupt services, or escalate privileges. The high CVSS score of 8.8 indicates significant risk.

Compliance Impact

This vulnerability could lead to unauthorized access, data breaches, or privilege escalation, potentially violating GDPR (data protection) and HIPAA (health data security) requirements. Compliance may be compromised due to exposure of sensitive information or system control.

Mitigation Strategies

Upgrade Langflow to version 1.10.2 or later immediately. Ensure all API endpoints require authentication and proper authorization. Remove any hardcoded default superuser credentials. Restrict access to MCP server configuration and file management endpoints.
