Security is extremely important to us at Humble Bundle. In addition to doing our best to make a secure product, we are opening up a streamlined process for the community to responsibly report any sort of security issues to us. We will be monitoring this very closely and sincerely thank anyone who helps us maintain our high security standards.

Please note that this page is intended for security researchers or other people who have found a technical bug in our website. If you are a customer who has a personal security issue such as your account being compromised or a question about billing, please contact our customer service team at https://support.humblebundle.com as soon as possible, instead of using this bug report form!

Researchers will receive Kudos points for all valid submissions, and the ability to donate up to $100 to the charity of their choice by leaving a comment in the submission.
