A vulnerability was determined in FoundationAgents MetaGPT up to 0.8.2. Affected by this issue is the function check_cmd_exists of the file metagpt/utils/common.py. This manipulation of the argument mermaid.path causes command injection. The attack may be initiated remotely. A high degree of complexity is needed for the attack. The exploitation is known to be difficult. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
Weakness
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
