Thanks for the submission. It's definitely cleaner to not to be expanding variables within a query string, and to rely instead on the underlying DBD's quoting utilities used in the parameter passing. At the same time, it's hard to see how this and most other instances of this type of sloppy expansion in Koha are exploitable in a useful manner unless you're enabling mysql_multi_statements => 1 at connect time, which we aren't doing. Well, I suppose in this case you could fudge $bookseller to be something like " 'anything' OR aqbasket.booksellerid IS NOT NULL" to get parcels for all the booksellers instead of just one. I don't know how useful that is, though, in terms of undermining the security considerations. Nevertheless, better to fix it than to find out the hard way it's more of an issue than thought!
