CVE-2026-9198 Scanner

IBM Langflow is an open-source software employed by various organizations for data processing and analytics purposes. It offers a platform for automating workflows and integrating diverse data systems. Businesses utilize Langflow for enhancing their data management capabilities, facilitating complex data flows, and streamlining operations. This software is frequently deployed in enterprises and data-driven environments where system efficiency and functionality are critical. IT teams often rely on Langflow for seamless data integration and processing. The software's ease of use and comprehensive feature set make it a popular choice among data engineers and analysts.

The Remote Code Execution (RCE) vulnerability in IBM Langflow is a critical security flaw allowing unauthenticated attackers to execute arbitrary code remotely. This vulnerability arises from inadequacies in the endpoint authentication process. Unauthenticated users can exploit this vulnerability by chaining specific API endpoints. It allows malicious actors to bypass normal authentication procedures and gain unauthorized access. This security issue is particularly severe as it can lead to a complete compromise of the affected system. The vulnerability poses a significant risk to data integrity and system security.

The technical details of this vulnerability involve chaining the /api/v1/auto_login and /api/v1/validate/code endpoints. These endpoints can be manipulated by attackers to bypass authentication and execute code. The exploit is facilitated by weaknesses in the endpoint validation process. Attackers can generate access tokens through these endpoints and use them for code execution. The crafted HTTP requests can manipulate the API to run arbitrary commands. This vulnerability demonstrates the importance of robust authentication mechanisms.

When exploited, this vulnerability can lead to severe consequences such as unauthorized access, data breaches, and system disruptions. The attackers can potentially take full control over the affected system. Such actions can lead to the leakage of sensitive information and the alteration of critical data. The exploitation could result in downtime or performance degradation of the compromised system. Unauthorized code execution can introduce malware or cause other malicious activities. Overall, the vulnerability puts the organization's information security at high risk.
