CVE-2025-57760 is a high-severity privilege escalation vulnerability affecting langflow-ai's Langflow product, versions up to and including 1.5.0. Langflow is a tool designed for building and deploying AI-powered agents and workflows, typically running within containerized environments. The vulnerability arises from improper privilege management (CWE-269) within Langflow containers. Specifically, an authenticated user who already has remote code execution (RCE) capabilities can invoke an internal command-line interface (CLI) command, 'langflow superuser', to create a new administrative user account. This escalation bypasses normal access controls, allowing a non-administrative user to gain full superuser privileges. The vulnerability does not require additional user interaction beyond authentication and RCE access, and it can be exploited remotely over the network (AV:N). The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. No public patch has been released at the time of publication, and no known exploits have been observed in the wild yet. The vulnerability's root cause is insufficient enforcement of privilege boundaries within the containerized environment, allowing misuse of internal CLI commands by users who should not have administrative rights. This flaw could lead to complete system compromise, unauthorized data access, and potential lateral movement within affected environments.

For European organizations, the impact of this vulnerability can be significant, especially for those leveraging Langflow in AI development, automation, or workflow orchestration. Successful exploitation grants attackers full administrative control over the Langflow environment, enabling them to manipulate AI agents, access sensitive data, disrupt workflows, or deploy further malicious payloads. This can lead to data breaches involving personal or proprietary information, violating GDPR and other data protection regulations, resulting in legal and financial penalties. Additionally, attackers could use the elevated privileges to pivot to other internal systems, increasing the risk of widespread compromise. Organizations relying on Langflow for critical AI operations may experience operational downtime or degraded service availability, impacting business continuity. The lack of a public patch increases the urgency for interim mitigations. Given the high CVSS score and the potential for full system compromise without user interaction, European entities must prioritize addressing this vulnerability to protect confidentiality, integrity, and availability of their AI infrastructure.

Since no official patch is currently available, European organizations should implement the following specific mitigations: 1) Restrict network access to Langflow containers, limiting exposure to trusted internal networks and authorized personnel only. 2) Enforce strict authentication and authorization controls to minimize the number of users with RCE capabilities, employing the principle of least privilege. 3) Monitor and audit usage of internal CLI commands within Langflow containers, especially any invocations of 'langflow superuser' or similar administrative commands, to detect suspicious activity promptly. 4) Employ container runtime security tools to detect and prevent unauthorized command executions or privilege escalations. 5) Isolate Langflow deployments in segmented network zones to contain potential breaches. 6) Prepare for rapid patch deployment by tracking vendor updates and testing patches in controlled environments before production rollout. 7) Consider temporary disabling or restricting the internal CLI if feasible, or implementing custom access controls around it until an official fix is released. 8) Conduct user training and awareness to recognize potential exploitation signs and report anomalies. These targeted measures go beyond generic advice by focusing on controlling access to the vulnerable functionality and enhancing detection capabilities.
