Miggo AIRoot Cause Analysis

The vulnerability stems from executing untrusted Python code containing os.system calls without validation. While exact implementation details aren't shown, the core issue exists in the code execution handler that processes the 'content' field from JSON input. The Go code runner's main execution function would be responsible for this unsafe code execution pattern, as evidenced by the PoC demonstrating direct command execution through Python's os.system.
