How to fix?

There is no fixed version for org.nanohttpd:nanohttpd.

Overview

Affected versions of this package are vulnerable to Information Exposure. Whenever an HTTP Session is parsing the body of an HTTP request, the body of the request is written to a RandomAccessFile when the it is larger than 1024 bytes. This file is created with insecure permissions that allow its contents to be viewed by all users on the host machine.

Workaround: Manually specifying the -Djava.io.tmpdir= argument when launching Java to set the temporary directory to a directory exclusively controlled by the current user can fix this issue.
