 * On a WP Multisite installation, with the plugin activated per site, is there 
   a risk that a subdomain might be able to change something in the database tables
   for another site? can it access the whole DB?
 * thanks

 * as far as I see – YES, the whole DB is affected. I could not found a function
   to choose special WP-site in multisite installation.

 * Right, the plugin will search/replace about all tables of the install, also MU.
   THis is a helper, to run easy SQL search, replaces, nut more, but not less.
