Research direction

The issue names containment statements and .swp files but no implementation files or tests. Start by locating the code that generates containment statements and reproduce the behavior with a temporary .swp file. Done means .swp files are excluded from containment statements without breaking other file handling, with relevant tests passing.

Written by the indexing model from the issue text.

Description

https://fileinfo.com/extension/swp

.swp file is created when a text editor like nano or vim opens a file in a directory. When the editor is closed, the swap file is removed.

While swap files exist in a directory, NSS includes them in containment statements.

My attempts to GET the .swp file resulted in a 404, but this could still be a potential risk. At the very least, it does expose information when it really shouldn't.

I suggest excluding .swp from containment statements.
