If you are a security researcher or have discovered a vulnerability

Reporting Issues

If you think you’ve found a security vulnerability in FreshBooks, contact us immediately via (PGP Key).

PGP Key ID: 0x1D3189FA
PGP Fingerprint: F95D 04F1 1B91 6B90 F4E5 BB6B B7A0 DA75 1D31 89FA

Please read the policy and program rules before reporting anything.


We will investigate all legitimate reports and make every effort to quickly correct any vulnerability. We ask in return that you:

  • Provide details of the vulnerability, including information needed to reproduce and validate the vulnerability and a Proof of Concept (POC)
  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our services
  • Do not modify or access data that does not belong to you
  • Give FreshBooks a reasonable time to correct the issue before making any information public
  • FreshBooks does not reward for security issues

Program Rules

  • When experimenting, please only attack test accounts you control. A PoC unnecessarily involving accounts of other end users or FreshBooks employee may be disqualified. It’s also good practice to tell us the accounts you are using for testing even when they are under your control.
  • Do not run automated scans without checking with us first.
  • Do not test the physical security of FreshBooks offices, employees, equipment, etc.
  • Do not test using social engineering techniques (phishing, spear-phishing, pretexting, etc.)
  • Do not perform DoS or DDoS attacks. You are welcome and encouraged to look for vulnerabilities that can be leveraged for DoS or DDoS attacks, we just don’t want you actually exploiting the issue outside of a tightly controlled environment.
  • Do not, in any way, attack our end users or engage in the trade of stolen user credentials.
  • Only the first reporter is eligible for getting into our Hall of Fame

FreshBooks uses a number of third-party providers and services. Our bug bounty program does not give you permission to perform security testing on their systems. Vulnerabilities in third-party systems will be assessed case-by-case, and most likely will not be eligible for a reward. The following third-party systems are excluded:

  • Direct attacks against any part of Google’s infrastructure
  • Plaid
  • Yodlee
  • PayPal
  • WePay
  • Zendesk
  • AWS
  • Fastly

Non-­qualifying Vulnerabilities

Low severity, purely theoretical and best-practice issues do not qualify for submission. Here are some examples:

  • Descriptive error messages (e.g. Stack Traces, application or server errors)
  • Theoretical sub-domain takeovers with no supporting evidence
  • HTTP 404 codes/pages or other HTTP non-200 codes/pages
  • Information leakage, fingerprinting / banner disclosure on common/public services
  • Disclosure of known public files or directories, (e.g. robots.txt)
  • Clickjacking on a public page and issues only exploitable through clickjacking
  • CSRF on forms that are available to anonymous users (e.g. the contact form)
  • Logout Cross-Site Request Forgery (logout CSRF)
  • Presence of application or web browser ‘autocomplete’ or ‘save password’ functionality
  • Lack of Secure/HTTPOnly flags on non-sensitive Cookies

  • Directory Listing
  • Missing HTTP security headers, (specifically OWASP list of useful HTTP headers)
  • SSL Issues (BEAST, BREACH, Renegotiation attack, Forward secrecy not enabled, weak ciphers)
  • Not performing rate limiting on non-login endpoints
  • Content spoofing
  • HPKP / HSTS preloading
  • Generic examples of Host header attacks without evidence of the ability to target a remote victim
  • Reports exploiting the behavior of, or vulnerabilities in, outdated browsers
  • SPF, DKIM, or DMARC settings & Email Spoofing
