It's not the wildcard (.*) that makes the expression tainted, but rather what's in $upload_dir and/or $in{'imgid'} (if they originate from program-external input), so you need to untaint those. update: actually, it's the glob itself that, too, returns tainted data (with or without '*').

See perlsec for how to do it.
