Rules

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

While testing

  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for a reward.
  • Submit one vulnerability per report unless you need to chain vulnerabilities to provide impact.
  • When duplicates occur, we only award the first report that was received (provided that it can be fully reproduced).
  • Multiple vulnerabilities caused by one underlying issue will be awarded one bounty.
  • Social engineering (e.g., phishing, vishing, smishing) is prohibited.
  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with 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 brute force 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
