Executive Summary

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]

Impact Analysis

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]
