Technical details
An OS command injection vulnerability exists in FoundationAgents MetaGPT versions up to and including 0.8.1. The flaw is located in the Bash.run function within the metagpt/tools/libs/terminal.py library, which fails to properly sanitize inputs before passing them to a system shell. A remote attacker can exploit this by providing malicious input—potentially via prompt injection if the tool is exposed to an LLM—to execute arbitrary commands on the host operating system. While a pull request (#1940) has been proposed to implement command validation and an allowlist, it has not yet been merged into the main project.
