Description
Langflow code Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Langflow. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the code parameter provided to the validate endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute Python code. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-27322.

Executive Summary

CVE-2026-0768 is a critical remote code execution vulnerability in Langflow. It occurs because the application does not properly validate user-supplied input in the 'code' parameter sent to the validate endpoint. This flaw allows remote attackers to execute arbitrary Python code on the affected system without needing to authenticate. [1]

Impact Analysis

This vulnerability can have a severe impact as it allows remote attackers to execute arbitrary code with root privileges on affected Langflow installations. This means attackers can take full control of the system, potentially leading to data theft, system compromise, or disruption of services. [1]
