Program rules

Required policies

We require that all researchers:

  • Do not access customer or employee personal information. If you accidentally access any of these, please stop testing and submit the vulnerability.
  • Do not degrade the user experience, disrupting production systems, or destroy data during security testing.
  • Use the WhiteHub report submission form to report vulnerability information to us.
  • Collect only the information necessary to demonstrate the vulnerability.
  • Submit any necessary screenshots, screen captures, network requests, reproduction steps or similar using the WhiteHub submission form (you can use third-party file sharing sites but you have to make sure they are not disclosed to anyone other than us).
  • When investigating a vulnerability, please only target your own account and do not attempt to access data from anyone else’s account.
  • It is compulsory for you to send all questions and reports to WhiteHub so that we can ensure your benefits and avoid any unnecessary problems. Please do not directly contact the business.
  • Public discussion about this program is not permitted
  • Your report is not allowed to disclose publicly without our consent. In case of the agreement reached, we can disclose your report on WhiteHub.

Violations will be dealt with by warning, refusing to reward or permanently banning the account on WhiteHub

Qualifying vulnerabilities

Any design or implementation issue that substantially affects the confidentiality or integrity of user data is likely to be in scope for the program. Common examples include:

  • Remote Code Execution
  • SQL Injection (SQLi)
  • Business Logic
  • Mobile-specific API vulnerabilities
  • Cross Site Scripting (XSS)
  • Cross-Site Request Forgery (CSRF)
  • Authentication-related issues
  • Authorization-related issues
  • Data Exposure

Non-qualifying vulnerabilities

Depending on their impact, some of the reported issues may not qualify. Although we review them on a case-by-case basis, here are some of the common low-risk issues that typically do not earn a monetary reward:

  • URL redirection
  • Bugs requiring exceedingly unlikely user interaction
  • Logout cross-site request forgery
  • Flaws affecting the users of out-of-date browsers and plugins.
  • Presence of banner or version information
  • Email spoofing
  • DDoS
