GROUPON WEBSITE RESPONSIBLE DISCLOSURE
Groupon’s Commitment to Security
At Groupon we are committed to maintaining the security of our systems and data. We believe that good security is critical to maintaining the trust of our customers, merchants and employees. As such, we strive to continuously improve our security to ensure that we are prepared to meet the challenges posed by an ever-evolving threat landscape.
Bug Bounty Program
We value your input. When properly notified of a security issue we are committed to working with you to understand and remediate verified problems. If you believe you find an issue on our site, we encourage you to report it to us in a private and responsible way. In order to encourage this, we have established a reward program which will pay a bounty for verifiable security issues reported to us through the proper channel.
What Vulnerabilities Qualify for the Bounty?
Although not an exhaustive list, any issue that potentially affects the confidentiality, availability, or integrity of our customer's data will be considered for a bounty. Some examples of those types of issues include:
- Cross-site scripting (XSS)
- Cross-site request forgery (CSRF)
- SQL/Code Injection
- Issues identified with our authentication or session management mechanisms
Similarly, we also have a number of issues for which we will generally not pay out a bounty - and which include anything that reports an act that is abusive or in bad faith. These include:
- Bugs identified via off the shelf vulnerability or security scanners including opensource / free / or commercial tools, i.e. burpsuite, Websecurify, Zed, Wikto.
- Infrastructure attacks, including brute force or denial of service
- Tools that generate significant amount of traffic volume or any activity deemed to be disruptive to other users
- Attacks against other user accounts(target your own account only)
- Bugs that we are already fixing or that someone else has previously reported
- Underspecified reports where the information provided is insufficient to reproduce the vulnerability
- Functionality bugs which do not compromise the security of our users’ accounts or personal information
- Bugs that have been disclosed publicly or to third parties (brokers) by you or others
- Vulnerabilities on sites that are not owned or operated by Groupon
- Testing a suspected vulnerability in a way that violates any law or compromises data that is not your own
- POC videos or other materials that prove the issue have been uploaded to third party website, even if marked as not publicly searchable
Reporting Suspected Vulnerabilities
If you believe that you have found a vulnerability, please report it to email@example.com. A written description is required if you are sending a POC video. Our security team will interact with you directly from there. We encourage the use of encryption in your communications with us and ask that you encrypt your message to us whenever possible. Our public PGP key can be downloaded from here and is located at the bottom of this page.
Please note that whether to award bounties and the bounty awarded for identified issues will vary and remain at all times at Groupon’s discretion. If multiple vulnerabilities are reported or are closely related, we may choose to only award a single bounty. We may choose not to award bounties when we launch new products for a beta period, or otherwise are actively in a development or upkeep cycle. We may also require documentation for tax reporting purposes before we are able to pay certain bounties and we are unable to award bounties to individuals or in situations where to do so would violate a sanction list maintained by the U.S. Office of Foreign Assets Control (“OFAC”) or conflict with the letter or spirit of other applicable State, Federal or Territorial law, rule or regulation. Notwithstanding any of the above, Groupon reserves the right to cancel or modify this program at any time and without notice.
