What an attacker can do
An unauthenticated remote attacker can use traversal, encoded traversal, absolute paths, or an unbounded path_index to read image-decodable files and enumerate host paths. get_model_preview (app/model_manager.py) built the path with os.path.join(folder, filename) where filename is an unrestricted {filename:.*} route capture. Vendor/CNA’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality impact as high; integrity and availability impact as none.
