Upgrade harp to version 0.40.2 or higher.
Overview
harp is a zero-configuration web server with built in pre-processing.
Affected versions of this package are vulnerable to Information Exposure. The documentation explicitly mentions that files or directories with names that start with an underscore are ignored by the server and are not served to the end user. By using simple URL encoding this verification is bypassed and files or directories that should be ignored are accessible.
