CodeQL caught a path where we were passing in req.query.path
to pathToFsPath, which may not have been a string.
So we refactored some things to ensure we only pass it a string
which also let us change the parameter type to string
instead of string | string[].
There's a chance this function can be called with a path that is not a string.
To catch that, we check if path is of a different type and throw an error if it
is.
This also adds a couple tests for this function.
This can be used to escape any special characters in a string with HTML before
sending from the server back to the client. This is important to prevent a
cross-site scripting attack.
Previously, we used argon2 to verify the hash with the password.
If the hash didn't start with a $, then it would enter the catch block.
Now we check the hash before trying to verify it and we also throw an Error if
the verify fails.
This makes the isHashMatch function more robust.
