Welcome to our vulnerability disclosure program on HackerOne!

KOHO looks forward to working with the security community to find vulnerabilities in order to keep our businesses and customers safe.

Response Targets

KOHO will make a best effort to meet the following response targets for hackers participating in our program:

• Time to first response (from report submit) - 10 business days

• Time to triage (from report submit) - 15 business days

We’ll try to keep you informed about our progress throughout the process.

Program Rules

• 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 only once.

• 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.

• Please send an email to support@koho.ca CCing security@koho.ca with any accounts that were used for testing so they can be removed.

Out of scope vulnerabilities

When reporting vulnerabilities, please consider (1) attack scenario / exploitability, and (2) security impact of the bug. The following issues are considered out of scope:

• Any activity that could lead to the disruption of our service (DoS)

• Rate limiting or bruteforce issues on non-authentication endpoints

• Vulnerabilities surrounding account/email enumeration and information gathering unless it leads to a serious data leakage

• Clickjacking on pages with no sensitive actions

• Tabnapbbing

• Self-XSS

• Open redirect - unless an additional security impact can be demonstrated

• 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

• Comma Separated Values (CSV) injection without demonstrating a vulnerability

• Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS

• Missing best practices in SSL/TLS configuration

• Missing best practices in Content Security Policy

• Missing HttpOnly or Secure flags on cookies unless it leads to a demonstrated security impact

• Missing email best practices (Invalid, incomplete or missing SPF/DKIM/DMARC records, etc.)

• Previously known vulnerable libraries without a working Proof of Concept

• Vulnerabilities only affecting unsupported mobile OS versions (iOS < 10.0, Android < 4.4)

• Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]

Safe Harbor

Any activities conducted in a manner consistent with this policy will be considered authorized conduct and we will not initiate legal action against you. If legal action is initiated by a third party against you in connection with activities conducted under this policy, we will take steps to make it known that your actions were conducted in compliance with this policy.

Thank you for helping keep KOHO and our users safe!
