Attack-Flow Graph

Executive Summary

CVE-2026-7754 is a Server-Side Request Forgery (SSRF) vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.0. It occurs due to an insecure default configuration where the SSRF protection mechanism could be disabled via the `ssrf_protection_enabled` setting. This allows authenticated users to bypass URL validation and make the server fetch arbitrary URLs, including cloud metadata endpoints, internal services, and Docker daemon APIs.

Detection Guidance

To detect this SSRF vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.0, check if the `ssrf_protection_enabled` setting is set to False in the configuration. Review server logs for unusual outbound requests to internal or cloud metadata endpoints like 169.254.169.254. Use network monitoring tools to identify unauthorized connections from the Langflow server to unexpected destinations.

Impact Analysis

An attacker with authenticated access could exploit this vulnerability to make the server send requests to internal or external systems. This could lead to unauthorized access to sensitive data, internal network reconnaissance, or interaction with cloud services, potentially resulting in data breaches or further attacks on the infrastructure.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating confidentiality requirements under GDPR and HIPAA. Organizations using affected versions may face compliance violations, legal penalties, and reputational damage due to potential data breaches resulting from the SSRF flaw.

Mitigation Strategies

Immediately upgrade Langflow OSS to version 1.10.1 or later, as this sets `ssrf_protection_enabled` to True by default. Ensure the SSRF protection mechanism is enabled and properly configured. Restrict network access to the Langflow server to prevent unauthorized outbound requests. Monitor for any suspicious activity or unauthorized connections.
