Executive Summary

This vulnerability is a critical remote code execution flaw in Foundation Agents' MetaGPT product. It exists in the function actionoutput_str_to_mapping, where the software improperly validates a user-supplied string before executing it as Python code. Because of this, a remote attacker can send malicious input that gets executed on the system without needing to authenticate, allowing them to run arbitrary code with the same privileges as the service account running MetaGPT. [1]

Impact Analysis

Exploiting this vulnerability allows a remote attacker to execute arbitrary code on your system with the privileges of the MetaGPT service account. This can lead to a full compromise of the affected installation, including unauthorized access, data manipulation, or disruption of services. [1]
