Affected versions of this package are vulnerable to Interpretation Conflict via the upload endpoints when reserved internal form fields are injected as query parameters or through parser differentials between Tornado and Flask. An attacker with file upload permissions can cause sensitive files from the host system to be moved into the upload folder, making them accessible for download, or potentially disrupt system availability by removing critical runtime files. This is only exploitable if the attacker possesses a user account with file upload permissions.
