## Summary

The agent-zero software from ModelScope contains a directory traversal flaw in its file browser component, which allows a user to supply file paths that are not properly checked or normalized. An attacker could use this to write files to locations outside the intended directory, potentially overwriting or creating sensitive files on the affected system.
