Executive Summary

IBM Langflow OSS versions 1.0.0 through 1.10.0 have a vulnerability where remote attackers can inject arbitrary code due to improper control of user input code.

Detection Guidance

This vulnerability involves improper input validation in IBM Langflow OSS versions 1.0.0 through 1.10.0, allowing remote code injection. To detect it, inspect running Langflow instances for versions within this range. Check logs for unusual code execution or unauthorized commands. Monitor network traffic for unexpected outbound connections from Langflow processes.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary code on the affected system, potentially leading to unauthorized access, data theft, or system compromise.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements such as GDPR or HIPAA, depending on the data exposed.

Mitigation Strategies

Update IBM Langflow OSS to a version beyond 1.10.0 to address the arbitrary code injection vulnerability. Ensure proper input validation and sanitization for user-provided code to prevent injection attacks.
