CVE-2026-13446 in Langflow
Summary
by MITRE • 07/17/2026
IBM Langflow OSS 1.0.0 through 1.10.1 contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.

This vulnerability in IBM Langflow Open Source Software versions 1.0.0 through 1.10.1 represents a critical security flaw that directly violates fundamental principles of secure system design and configuration management. The presence of hard-coded credentials within the application's codebase creates an inherent weakness that persists across all instances of the software deployment, making it particularly dangerous for widespread adoption in enterprise environments where security posture is paramount.
The technical implementation of this vulnerability involves embedded authentication tokens, passwords, or cryptographic keys directly encoded within the source code or configuration files of the Langflow application. These credentials are typically used for inbound authentication mechanisms that verify user access to the system's administrative interfaces or internal APIs, outbound communication protocols that establish trust with external services such as databases, cloud storage systems, or third-party integrations, and encryption processes that secure sensitive data at rest within the application's internal storage mechanisms. The hard-coded nature of these credentials means they cannot be dynamically updated or rotated without requiring code modification and re-deployment, creating a persistent attack surface.
From an operational impact perspective, this vulnerability creates significant risk for organizations deploying IBM Langflow in production environments. Attackers who gain access to the source code or can perform static analysis on deployed instances can immediately extract these credentials and leverage them to authenticate as legitimate users or system components. This access could enable unauthorized data exfiltration, modification of internal configurations, or lateral movement within network environments where Langflow is integrated with other systems. The vulnerability particularly affects scenarios involving cloud deployments, containerized environments, or microservices architectures where the application communicates with multiple external services using these hard-coded credentials.
The security implications extend beyond simple credential exposure to encompass broader compliance and risk management concerns. Organizations implementing this software face potential violations of regulatory requirements such as those outlined in pci dss, hipaa, and iso 27001 standards that mandate proper credential management and access control mechanisms. The vulnerability directly maps to CWE-798, which specifically addresses the use of hard-coded credentials in software applications, and aligns with ATT&CK technique T1552.001 for "Unsecured Credentials" and T1078.004 for "Valid Accounts: Cloud Accounts" when these credentials are used to access cloud-based components.
Effective mitigation strategies must address both immediate remediation and long-term architectural improvements. Organizations should immediately replace all hard-coded credentials with secure credential management solutions such as vault systems, environment variable injection, or configuration management tools that support dynamic credential rotation. The software should be updated to version 1.10.2 or later if available, or code modifications should be implemented to eliminate embedded credentials and implement proper authentication mechanisms. Additionally, security teams should conduct comprehensive audits of all deployed instances to ensure no residual hard-coded credentials remain in the system configuration or deployment artifacts. Regular security scanning should include checks for hardcoded secrets in source code repositories, container images, and deployment packages to prevent recurrence of similar vulnerabilities in future releases.
