At Hyatt Hotels Corporation, our mission is to provide authentic hospitality
by making a difference in the lives of the people we touch every day. In
keeping with this mission, we respect fundamental human rights, as embodied in
the Universal Declaration of Human Rights.
Keeping Guests Safe
Hyatt takes the security of our guests and colleagues very seriously. By being
the first organization in the hospitality industry to embrace the
collaborative efforts of global security researchers, Hyatt hopes to continue
to raise its already high level of security standards as well as learn from
and collaborate with security researchers. If you have information about a
qualified security vulnerability that is within our predetermined scope, we
would love to hear from you!
In-scope vulnerabilities will be rewarded based on severity following
remediation. The Hyatt Bug Bounty program will only accept HackerOne
vulnerability reports containing original and validated vulnerabilities that a
potential attacker could use to compromise the confidentiality, integrity, and
or availability of the services in scope.
By participating in the Hyatt Bug Bounty program you agree to follow all of
the requirements below.
Hyatt Hotels looks forward to working with the security community to find
security vulnerabilities in order to keep our businesses and customers safe.
Hyatt Hotels will make a best effort to meet the following SLAs for hackers
participating in our program:
- Time to first response (from report submit) - 1 business days
- Time to triage (from report submit) - 1 business days
- Time to bounty (from triage) - Once vulnerability is remediated, bounty payout will occur
Critical = 30 days
High = 60 days
Medium = 90 days
Low = N/A
We’ll try to keep you informed about our progress throughout the process.
- Do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization.
- Follow HackerOne's disclosure guidelines __.
