Name of the Vulnerable Software and Affected Versions FoundationAgents MetaGPT versions prior to 0.8.3

Description Command injection is possible via the mermaid.path argument in the check cmd exists() function located in the metagpt/utils/common.py file. This issue allows a remote attacker to execute arbitrary commands, although the attack requires a high degree of complexity and is considered difficult to exploit.
