Executive Summary

IBM Langflow OSS versions 1.0.0 through 1.11.2 are vulnerable to server-side request forgery (SSRF). This flaw allows a remote attacker to send crafted requests from the affected server to internal or external systems, potentially accessing sensitive data or services.

Impact Analysis

An attacker could exploit this to access internal resources, exfiltrate sensitive data, or interact with other systems as if they were the vulnerable server. This may lead to unauthorized information disclosure or further attacks on connected systems.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating confidentiality requirements in GDPR and HIPAA. Organizations may face compliance violations, legal penalties, and reputational damage if sensitive data is exposed due to SSRF.

Mitigation Strategies

Update IBM Langflow OSS to the latest version beyond 1.11.2 to address the server-side request forgery vulnerability. Monitor network traffic for unusual requests and restrict access to sensitive endpoints.
