Rules

What the policy asks of you, and the bug types it won't reward, quoted from Payoneer (via HackerOne)'s policy. "We" in these lines means the program, not this site.

While testing

  • You need to show that you could exploit a vulnerability, but avoid causing any damage.
  • Submit one vulnerability per report, unless you need to chain vulnerabilities to reflect aggregative impact.
  • When duplicates occur, we only award the first report that was received with respect to the same vulnerability (provided that it can be fully reproduced).
  • Multiple vulnerabilities caused by one underlying issue will be eligible for one award.
  • Any type of social engineering (e.g. phishing, vishing, smishing) is strictly prohibited and vulnerabilities detected based on such conduct will not be eligible for awards.
  • Participants are required to avoid privacy violations, processing of any personal data, destruction of data, and interruption or degradation of Payoneer’ services.
  • Only use accounts you own and do not interact with other users’ accounts or data without explicit permission of the account holder.

Not accepted

  • Clickjacking on pages with no sensitive actions
  • Cross-Site Request Forgery (CSRF) on unauthenticated forms or forms with no sensitive actions
  • Attacks requiring MITM or physical access to a user's device.
  • Previously known vulnerable libraries without a working Proof of Concept.
  • Comma Separated Values (CSV) injection without demonstrating a vulnerability.
  • Missing best practices in SSL/TLS configuration.
  • Any activity that could lead to the disruption of our service (DoS).
  • Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
  • Rate limiting or bruteforce issues on non-authentication endpoints
  • Missing best practices in Content Security Policy.
  • Missing HttpOnly or Secure flags on cookies
  • Missing email best practices (Invalid, incomplete or missing SPF/DKIM/DMARC records, etc.)
  • Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]
  • Software version disclosure / Banner identification issues / Descriptive error messages or headers (e.g. stack traces, application or server errors).
  • Public Zero-day vulnerabilities that have had an official patch for less than 1 month will be awarded on a case by case basis.
  • Tabnabbing
  • Open redirect - unless an additional security impact can be demonstrated
  • Issues that require unlikely user interaction
