Bug Bounty

Report a Security or Privacy Vulnerability

TaxDome’s Bug Bounty Policy applies to security vulnerabilities found within its public-facing online environment.


The purpose of the Policy is to establish the rules for the review, evaluation, application, and verification of system updates to mitigate vulnerabilities in the IT environment and the risks associated with them. If you believe you have discovered a security or privacy vulnerability in the TaxDome product, please report it to us.

  • Add to any Block List

In case you suspect that a vulnerability of this kind exists, please contact TaxDome development team at

Severity levels

We classify vulnerabilities based on their potential impact on our systems. This helps us prioritize fixes and determine appropriate rewards. The severity levels are:

  • SEV-1 (low severity): there’s no way to exploit the vulnerability currently, but it has potential weaknesses that could be exploited in the future. 
  • SEV-2 (medium severity): the vulnerability allows an attacker to have a minor or limited impact on system operation. This might involve limited data access or bypassing minor restrictions.
  • SEV-3 (high severity): the vulnerability significantly impacts the operation of the entire system or allows an attacker to circumvent restrictions on a limited set of data.
  • SEV-4 (critical severity): the vulnerability significantly impacts the entire system or allows easy access to a significant amount of data by an attacker.
  • SEV-5 (extreme severity): the vulnerability grants an attacker complete and undetectable access to the system. 

Examples of Vulnerabilities by Severity

Here are some examples of vulnerabilities classified by their severity level: 

  • SEV-1 (low severity): HTML injection/malicious code/URL injection; open redirect
  • SEV-2 (medium severity): DOS (denial of service) attack possibility; employee without necessary rights can get access to the organizer and organizer template
  • SEV-3 (high severity): an attacker can steal a user’s clients and can link the clients to their contacts via IDOR (Insecure Direct Object References)
  • SEV-4 (critical severity): an attacker can get unauthorized access to delete invoices of all users via IDOR 
  • SEV-5 (extreme severity): an attacker can inject arbitrary code that allows them to completely take over a user’s account, steal their data, and perform actions undetected on their behalf

Protecting Our Clients from Phishing

TaxDome is committed to protecting our clients from phishing attacks. Phishing emails are fraudulent attempts to trick recipients into revealing sensitive information, such as usernames, passwords, or financial data. Sometimes, these emails appear to be from legitimate sources, such as a firm owner using TaxDome.

What to Look Out For

Phishing emails can be very convincing, but there are some red flags to watch out for:

  • The email address might look similar to a legitimate sender but have slight variations (e.g. one extra character or a different domain name)
  • The email might address you generically instead of by your name
  • The email might create a sense of urgency or pressure to act quickly
  • Phishing emails often contain grammatical errors or typos

If you receive a suspicious email claiming to be from your firm owner or TaxDome, please do not click on any links or attachments.

Reporting Phishing Attempts

While we appreciate your vigilance, please note that reports about phishing attempts are not eligible for our Bug Bounty program. Our program focuses on identifying vulnerabilities within the TaxDome platform itself.

Program Rules

Please note that we only pay fees for original reports. If a duplicate is registered, we will inform you when the first report is filed.

Ineligible Reports:

  • Everything that is not under our control (third-party services, including but not limited to, featureOS, Intercom, Beamer,
  • Everything that requires physical access to device or network
  • Everything that requires outdated versions of software or hardware
  • Social engineering, phishing etc.
  • Recommendations and best practices, as long as there is no specific exploit
