CVE-2025-57760 in Langflow
Summary
by MITRE • 08/26/2025
Langflow is a tool for building and deploying AI-powered agents and workflows. A privilege escalation vulnerability exists in Langflow containers where an authenticated user with RCE access can invoke the internal CLI command langflow superuser to create a new administrative user. This results in full superuser access, even if the user initially registered through the UI as a regular (non-admin) account. A patched version has not been made public at this time.

The vulnerability CVE-2025-57760 represents a critical privilege escalation flaw within the Langflow platform, which is designed for constructing and deploying AI-powered agents and workflows. This security weakness specifically affects containerized deployments of Langflow and creates a pathway for authenticated users to bypass normal access controls. The vulnerability manifests through the internal CLI command langflow superuser which can be invoked by users who already possess remote code execution capabilities within the system. This presents a particularly dangerous scenario as it allows attackers to escalate their privileges from a standard user account to full administrative access without requiring additional authentication mechanisms or elevated permissions.
The technical implementation of this vulnerability stems from inadequate privilege validation within the Langflow application's internal command processing system. When an authenticated user with existing RCE access invokes the langflow superuser command, the system fails to properly verify whether the requesting user should possess administrative privileges. This flaw directly relates to CWE-284 which describes improper access control mechanisms, specifically the lack of proper authorization checks for administrative functions. The vulnerability exists in the command-line interface processing logic where the system trusts the invocation of administrative commands without sufficient verification of the user's legitimate administrative rights.
The operational impact of this vulnerability is severe and far-reaching for organizations utilizing Langflow in containerized environments. An attacker who has already gained initial access to the system through other means can immediately escalate their privileges to full administrative control, effectively neutralizing any user account restrictions that were previously in place. This means that even users who initially registered through the standard user interface as non-administrative accounts can be elevated to superuser status, bypassing the intended multi-level access control architecture. The implications extend beyond simple privilege escalation as the attacker now has complete control over the Langflow deployment, including the ability to modify workflows, access sensitive data, and potentially use the platform as a pivot point for further attacks within the network infrastructure.
Organizations should immediately implement mitigations to address this vulnerability while a patched version remains unreleased. The most effective immediate solution involves restricting access to the internal CLI functionality through network segmentation and access control measures, ensuring that only authorized administrative personnel can invoke the langflow superuser command. Additionally, implementing strict command execution monitoring and logging should be enforced to detect any unauthorized attempts to escalate privileges. The principle of least privilege should be strictly enforced by limiting the number of users who possess RCE access within the Langflow environment, and implementing additional authentication layers for any administrative command execution. This vulnerability demonstrates the critical importance of proper authorization checks in all system interfaces, particularly within internal command processing functions, aligning with ATT&CK technique T1078 which covers valid accounts and privilege escalation through legitimate system access. Organizations should also consider implementing runtime application self-protection mechanisms and privilege separation to reduce the attack surface and prevent unauthorized privilege escalation attempts.
