Multiple giftcard sites suffer from cross site scripting vulnerabilities. The vendor has failed to make good on their bug bounty program claiming they are duplicate findings but has never addressed the issues.

Giftcard Cross Site Scripting

Since November 2013 I reported seven Cross-site Scripting
vulnerabilities to the Giftcard Bug Bounty Program. Sadly, only one of
them wasn't a duplicate :-/. Strange? Perhaps, but not impossible
given the simplicity of the vulnerabilities.

But what I really don't understand: Why do they still work until today?
