Executive Summary

IBM Langflow OSS versions 1.0.0 through 1.12.4 have a vulnerability where a remote authenticated attacker can access sensitive information. This occurs because the software does not properly restrict file paths, allowing unauthorized access to restricted directories.

Compliance Impact

This vulnerability could result in unauthorized data exposure, violating GDPR (data protection) and HIPAA (health information privacy). Non-compliance may lead to legal penalties, fines, or reputational damage for organizations handling regulated data.

Mitigation Strategies

Update IBM Langflow OSS to version 1.12.4 or later to address the improper pathname restriction issue. Ensure only authenticated users have access to sensitive directories and review permissions for remote access.
