Description
Langflow eval_custom_component_code Eval 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 implementation of eval_custom_component_code function. 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 the current process. Was ZDI-CAN-26972.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a critical remote code execution flaw in Langflow's eval_custom_component_code function. It occurs because the function executes user-supplied strings as Python code without proper validation. This allows remote attackers to run arbitrary code on affected systems without needing to authenticate. [1]


How can this vulnerability impact me? :

An attacker can exploit this vulnerability to execute arbitrary code remotely on your Langflow installation. This can lead to full compromise of the affected system, including unauthorized access, data theft, system manipulation, or disruption of services. [1]
