## Technical details

The vulnerability is a path traversal flaw in the agentic_data_api.py skill_upload endpoint that fails to properly validate user-supplied filenames. An unauthenticated remote attacker can craft requests with path traversal sequences (e.g., "../") to write files outside the designated workspace directory. The API accepts file uploads without sanitizing the path, enabling arbitrary file write capabilities.
