Security is the utmost highest priority at Enjin. Despite the heavy attention to detail, we understand that bugs are present within all pieces of technology - that includes our own. It's for that reason why we love to work with talented security researchers, around the world, to assist us in identifying and securing our systems and applications.

If you suspect that you've identified a security bug within any of our services, that are listed as "In Scope," then we will gladly work with you in order to ensure a rapid resolution of that issue and (for both your time and ethical disclosure) we will compensate you for your discovery.

Scope

Please refer to the "Scopes" section (below) for information about what assets we consider as being "In Scope." Vulnerabilities reported against any other assets are considered Out of Scope, and therefore will not be eligible for any bounty.

Note that the /cdn-cgi/* path is controlled by our Content Delivery Network, Cloudflare. Therefore, any submissions pertaining to this path will be marked as Out of Scope and therefore Not Applicable.

Responsible Disclosure

We respect the work that the security research community provides and we ask that you act in good faith when working with us. For that reason, we ask that you abide by the following whilst participating within our program:

• Limit testing to accounts you own and do not impact other users. If you encounter any user data, including but not limited to usernames, emails, or passwords, please report it to us immediately and stop testing right away.

• When testing, you should only do the minimum required to validate a vulnerability. In cases where it may impact our systems or users, please get in-touch with security@enjin.io first to confirm whether you have permission to proceed. No matter what the case is, never damage or leave any system in a more vulnerable state than when you discovered it.

• Do not follow "the rabbit hole" by continuing to dig deeper (look more thoroughly) into our system. Should you gain access to any of our systems, you should immediately stop and responsibly disclose the vulnerability.

Response Targets

Enjin has set forth the following response targets upon receiving a report:

• First response within 72 business hours;

• Triage within 7 business days;

• Have a resolution in place within 30 business days; and

• Payout within 14 business days after a resolution has been confirmed.

Whilst these are our baseline response targets, we will do our best to always exceed these targets.

However, in very limited circumstances, we may fail to meet one (or more) of these targets. In the event we fail to meet one of our targets, please be patient with us, as it will almost certainly come down to the complexity of the issue at hand. If no formal resolution has been made within 180 days and with no feedback from the Enjin security team in relation to why that's the case, and as a last resort, then the contents of the report may be publicly disclosed by the finder.

Eligibility

You will qualify for a reward if you are the first person to disclose an issue that is not yet known to us and one that affects an asset that's listed as both in-scope and eligible for bounties. You will qualify for a reward if you adhere to the following:

• You must report a vulnerability within 24 hours of its discovery.

• You must not disclose any details about the vulnerability anywhere else, this includes our support channels.

• You must provide clear steps in order to reproduce the reported vulnerability.

• You must not perform any automated tests / scans against our network.

• You must not perform any attacks that will result in high volumes of traffic (such as Denial of Service attacks.)

• You must avoid any tests that may cause service degradation / interruption.

• You must stop any tests in the event degradation / interruption is identified as a potential result of your tests.

• You must not access; download; leak; manipulate; or destroy any user data.

• You must not save any copies of data acquired through a vulnerability.

• You must only test with accounts that you have created and actively own.

• You must use your [username]@wearehackerone.com email address when testing authenticated routes.

• You must set the header X-H1-Username: [username] when performing tests outside of the browser (eg. via Postman / cURL / etc.)

• Your vulnerability must not fall within our list of Prohibition or Exclusions (as detailed further, below.)

Rewards

If you meet the eligibility criteria, listed above, and have responsibly disclosed a valid vulnerability then you will qualify for a reward.

Monetary Compensation

Enjin rewards researchers that submit eligible reports for qualifying vulnerabilities. In those cases, our minimum reward is US$60 and our maximum reward is US$1,500. The amount rewarded will vary depending on the severity of the vulnerability reported. Payments will be made directly via HackerOne's payout system.

Swag

Swag may be awarded, as a discretionary bonus, for a valid report against an in scope asset. Swag is limited to no more than one per researcher. We will not honour (nor respond to) repeated requests to be awarded swag, this is exclusively awarded at the discretion of the Enjin security team.

Prohibition
