Technical details
The File Download API's _validate function in src/octoprint/server/api/files.py fails to properly sanitize the filename argument, allowing path traversal attacks via directory traversal sequences. An unauthenticated remote attacker can exploit this to access files outside the intended download directory. A fix is available from the vendor.
