Please note: This program does not allow disclosure. You may not release information about vulnerabilities found in this program to the public.

Zynga Inc. is an American social game developer running social video game services.

Zynga invites you to test and help secure our publicly accessible web presence and games. We're highly interested in knowing about any vulnerabilities that may extend to any web-based property we own/control (online games, etc). We appreciate your efforts and hard work in making the internet more secure and look forward to working with the researcher community to create a meaningful and successful bug bounty program. Good luck and happy hunting!


For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.

This program only awards points for VRT based submissions.

Any game or FQDN domain/property of Zynga not listed in the targets section is out of scope. This includes any/all subdomains not listed above. Non-Zynga managed services (Third-Party) services integrated with, or used by Zynga games on non-Zynga FQDN DNS domains are out of scope. If you believe you've identified a vulnerability on a system outside the scope, please reach out to support@bugcrowd.com before submitting.

Zynga Services Info:


Researchers are free to self-provision or utilize any existing accounts they own - DO NOT test against any accounts you do not expressly own. If/when registering for testing purposes, please do so using your @bugcrowdninja.com email address. For more info regarding @bugcrowdninja email addresses, see here.

Testing Notes:

  • When testing or submitting against any forms that may go to a person on the other end (e.g. contact, support, etc), please be sure to include "Bugcrowd Testing -- Disregard" with your payloads.
  • When testing against any forms that may result in publicly facing content (e.g. "as a question" - please delete your post immediately after you've reviewed the outcome of your attempted attack). e.g. on community pages, etc
  • Note that you're free to self-provision any accounts that you're able to (e.g. community, etc).

No pre-provisioned accounts will be provided for this program.

API vulnerabilities in the following areas:

  • Filed in duplicate for the same service endpoint (HTTP-TLS + HTTP) URI paths to the SAME resource
  • Filed without screenshots and videos for proof of concept, and/or without the artifacts and evidence
