If you discover a bug / exploit / vulnerability on Newgrounds, you can PM Tom directly or email support@newgrounds.com with a report.
We appreciate a detailed explanation and clear steps to reproduce the bug or exploit.
It is also much appreciated if you keep the issue private until after a fix has been put in place.
Bug Bounties
We generally don't award payments for bugs that can't cause real harm, although we greatly appreciate having them reported to us.
If you find something that causes harm, we do offer bug bounties but please manage your expectations because we are a small company that has been operating at a loss for the past decade. Bounties have generally been in the $10-50 range. Occasionally we have managed to be more generous but please don't expect it.
