That program acts as a filter, using PATH_TRANSLATED feature to
access html files on your server tree, and it translates <! sql ...> tags
into html viewable text, letting other parts of the html file unchanged.

The problem is that www-sql performs nothing to verify if a user can
access the intended PATH_TRANSLATED file.

So, suppose your htdocs tree is /home/htdocs/
you have a subdirectory /home/htdocs/protected/ in which you have
you have restricted access using .htaccess file.
In your browser, enter URL http://your.server/protected/something.html:
you get prompted a username and a password.
Now, enter URL http://your.server/cgi-bin/www-sql/protected/something.html:
you get the requested file

www-sql is available into Incoming sunsite directory

This is a common characteristic of other "cgi-wrapper" programs as well,
including w3-msql and php.cgi. The latter addresses this by giving one
the option to set PATTERN_RESTRICT at compile time (that way it will
only load files ending in say ".phtml"), or by compiling as an apache
module. I'm not sure about w3-msql because I haven't been following it
for quite some time.
