Executive Summary

IBM Langflow OSS versions 1.0.0 through 1.10.2 have a vulnerability where a remote authenticated attacker could access sensitive information. This happens because the software does not properly restrict file paths, allowing unauthorized access to restricted directories.

Impact Analysis

This vulnerability could allow attackers to steal sensitive data, such as user credentials or confidential files, if they gain authenticated access to the system. It may lead to data breaches or unauthorized information disclosure.

Compliance Impact

This vulnerability could violate compliance requirements like GDPR or HIPAA by exposing sensitive personal or health data. Organizations may face legal penalties, fines, or reputational damage due to unauthorized data access.

Mitigation Strategies

Update IBM Langflow OSS to a version beyond 1.10.2 to address the improper pathname restriction issue. Ensure only authenticated users have access to sensitive directories and review file permissions to prevent unauthorized access.
