Executive Summary

This vulnerability allows authenticated users to exploit a built-in Langflow component to read arbitrary server environment variables. This exposes sensitive secrets even when security controls are in place to disable custom components.

Detection Guidance

To detect this vulnerability, check if your Langflow OSS version is between 1.0.0 and 1.10.3. Verify if authenticated users can access environment variables through built-in components. Review logs for unusual access to sensitive data.

Impact Analysis

An attacker with access could steal secrets like API keys or passwords, leading to unauthorized system access, data breaches, or further attacks within the environment.

Compliance Impact

Exposure of sensitive data violates compliance requirements for GDPR and HIPAA, which mandate protection of personal and health information. This could result in legal penalties or loss of certification.

Mitigation Strategies

Upgrade Langflow OSS to version 1.11.0 or later to mitigate the risk of unauthorized access to sensitive information.
