Lifecycle Timeline
4Description
A flaw has been found in FoundationAgents MetaGPT up to 0.8.1. This vulnerability affects the function ActionNode.xml_fill of the file metagpt/actions/action_node.py of the component XML Handler. Executing a manipulation can lead to improper neutralization of directives in dynamically evaluated code. The attack may be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through a pull request but has not reacted yet.
Analysis
Remote code injection in FoundationAgents MetaGPT up to version 0.8.1 allows unauthenticated attackers to execute arbitrary code via improper neutralization of directives in the ActionNode.xml_fill XML handler function. The vulnerability has publicly available exploit code and affects the dynamic code evaluation mechanism in metagpt/actions/action_node.py, enabling attackers to manipulate XML input for code injection with low complexity and no authentication required.
