Official description

DeepInfer through 0.1.0 contains a path traversal vulnerability in the unauthenticated /profile endpoint that allows remote attackers to create arbitrary directories via the output_dir parameter. Attackers, including cross-site GET requests from an operator's browser, can write chrome trace files to exhaust disk or inodes and use error messages as a filesystem oracle.
