Summary

Several years ago, @cyber__sec placed a cross-site scripting payload in the name of a staff member on his test shop. This payload recently executed in our internal administration panel, alerting us to a cross-site scripting bug. Because @cyber__sec's payload triggered the bug, we asked him to submit a report.

We awarded the maximum bounty under our Cross-site scripting category because the payload executed in our internal administrator panel, resulting in a high security impact.

How it was found

Hi all,

I had lots of tests for bug bounty in my test store "trstore-3.myshopify.com" (created about 4 years ago) and then one of your developers noticed that a stored cross-site scripting payload in my staff name fired in another your internal panel.

I have attached the email sent to me by your collegue and I'd like to get a award and I am very happy.

Thanks alot.
