Executive Summary

This vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.3 allows an authenticated attacker to access, modify, or expose sensitive host files via Docker-based MCP servers. The issue stems from insufficient filtering of dangerous Docker volume-mount and device-mapping arguments, enabling unauthorized file operations.

Detection Guidance

Check for Docker-based MCP servers in your Langflow deployment. Inspect Docker volume mounts and device mappings for suspicious paths or permissions. Look for containers running with elevated privileges or host filesystem access.

Impact Analysis

An attacker could exploit this to read confidential data, alter critical files, or leak sensitive information from the host system. This may lead to data breaches, system compromise, or unauthorized access to protected resources.

Compliance Impact

This vulnerability could violate compliance requirements such as GDPR or HIPAA by enabling unauthorized access to personal or health data. Organizations may face legal penalties, reputational damage, and loss of trust due to non-compliance resulting from this security flaw.

Mitigation Strategies

Upgrade Langflow to a version beyond 1.10.3. Review and restrict Docker volume mounts and device mappings in MCP servers. Remove unnecessary host filesystem access permissions. Ensure authenticated access controls are enforced.
