Rules
What the policy asks of you, and the bug types it won't reward, quoted from On (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 may not be marked as triaged.
-
Submit one vulnerability per report, unless you need to chain vulnerabilities to provide impact.
-
When duplicates occur, we only triage the first report that was received (provided that it can be fully reproduced).
-
Multiple vulnerabilities caused by one underlying issue will be treated as one valid report.
-
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.
-
Subdomain takeover without a working Proof of Concept.
-
Comma Separated Values (CSV) injection without demonstrating a vulnerability.
-
Missing best practices in SSL/TLS configuration.
-
User enumeration
-
Any activity that could lead to the disruption of our service (DoS).
-

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).
-
Tabnabbing
-
Open redirect - unless an additional security impact can be demonstrated
-
Issues that require unlikely user interaction
-
GraphQL introspection
-
Public access to S3 buckets or similar that only hold static assets
-
Special note: We know about the self-XSS on the chatbot. This falls under "unlikely user interaction".
