How do I best describe the vulnerability?
Please provide a detailed description of the vulnerability. Include details of how to exploit it (e.g. proof of concept), and the browser or settings required to reproduce it.

Join the great bug hunt!

We want to give players and security researchers around the world the opportunity to report security vulnerabilities with real-world impact in our applications.

No technology is perfect. Gameforge believes that working with skilled security researchers across the globe is essential to identifying and mitigating meaningful security risks. If you believe you've found a security issue in one of our products or services, we encourage you to notify us.

We highly value well-documented reports that clearly demonstrate business, user, or security impact, ideally supported by a proof of concept (PoC). Reports that focus solely on missing best practices, theoretical weaknesses, or hardening opportunities without a demonstrable impact are generally treated as informational.

Interested? You can find all important details in the FAQ and rules.

Participate in the Vulnerability Disclosure Program

Requirements

To participate in our Vulnerability Disclosure Program, you must adhere to the following:

Legal representatives and current or former employees of the Gameforge group and associated companies, as well as their spouses and relatives, are excluded from potential bounties.

Minors may only participate with the consent of their parents or legal guardians.

Our Commitment
(Rules for Gameforge)

  • We will ensure that reported vulnerabilities are triaged and handled as quickly as possible.
  • We will review your report promptly and provide feedback where appropriate.
  • We will keep you informed about the status of your report.
  • As long as you follow the rules below, you will not face legal action for responsible testing and disclosure.

Your Responsibilities (Rules for You)

Please follow these rules to ensure responsible disclosure and to avoid negative impact on our players, employees, or infrastructure:

  • You must not attack, exploit, alter, or otherwise compromise the accounts of third parties (players, employees, etc.). Where possible, only use your own accounts for testing.
  • DDoS, spam, or other disruptive attacks on our infrastructure are strictly prohibited, including social engineering and phishing.
  • Vulnerabilities must not be exploited for personal gain or to the detriment of third parties.
  • Vulnerabilities must be reported exclusively to Gameforge and must not be disclosed publicly or to third parties before we have fixed them.
  • The use of automated scanners or large-scale automated testing tools is not permitted.
  • Social engineering of Gameforge staff or game teams is not allowed.
  • Only the websites and services explicitly listed as part of the program may be tested.
What can be reported?

Vulnerabilities That Do Not Need to Be Reported

To help us focus on issues with actual security or business impact, please do not report the following:

  • Issues that only affect obsolete or unsupported browsers or plug-ins
  • Vulnerabilities that require extremely unlikely or unrealistic user behavior (e.g. manual copy & paste, deliberate deactivation of security features)
  • Insecure cookie settings for cookies that do not contain confidential or sensitive data
  • Disclosure of information that presents no meaningful risk or is already publicly accessible
  • Vulnerabilities in third-party software or services used by Gameforge
  • Vulnerabilities in applications or domains not listed as part of the Gameforge Vulnerability Disclosure Program
  • Missing security best practices, hardening suggestions, or configuration recommendations without a demonstrated exploit path or impact (these may be treated as informational)

Scope – Where Can I Hunt for Bugs?

Gameforge develops and operates a variety of web applications and games, and also publishes games developed by third parties while using third-party services.

Only vulnerabilities in software and services developed and managed by Gameforge are eligible for this program. Vulnerabilities in third-party software are excluded.

That said, we appreciate every report we receive. If you identify an issue in third-party software, we are happy to forward your report to the respective vendor on your behalf, if you wish.

To avoid misunderstandings, please consult the FAQ for the full and up-to-date list of domains and applications that are in scope for the Vulnerability Disclosure Program.

Any more questions?

FAQ

This FAQ contains answers to the most commonly asked questions. If you have a question that is not answered here, you can contact us at any time at vdp@gameforge.com.

Which domains are part of the Vulnerability Disclosure Program?

You can go bug hunting on the following domains:

  • *.gameforge.com
  • *.gameforge.de
  • *.gfsrv.net
  • Our games

Have you found a bug in a Gameforge application somewhere beyond these domains? We’re grateful for every bug report we receive and will gladly forward your reports to the respective developers in your name – if you so wish.

Out-of-Scope Vulnerabilities

In addition to the topics covered by Vulnerabilities that don’t need to be reported above, the following vulnerabilities are also not in the scope of our Vulnerability Disclosure Program:


  • Attacks requiring physical access to a user's device
  • Self-XSS (we require evidence on how the XSS can be used to attack another Gameforge user)
  • Issues without clearly identified security impact, such as clickjacking on a static website, missing security headers, or descriptive error messages
  • Lack of CSRF tokens (unless there is evidence of actual, sensitive user action not protected by a token)
  • Login/Logout CSRF
  • Our policies on presence/absence-content of SPF, DKIM, MTA-STS, and DMARC records
  • Host header injections unless you can show how they can lead to stealing user data
  • Absence of rate limiting, unless related to authentication
  • Missing security headers which do not lead directly to a vulnerability
  • Vulnerabilities only affecting users of outdated or unpatched browsers and platforms
  • Password, email and account policies, such as email id verification, reset link expiration, password complexity
  • Use of a known-vulnerable library (without evidence of exploitability)
  • Reports from automated tools or scans
  • Reports of insecure SSL/TLS ciphers (unless you have a working proof of concept, and not just a report from a scanner)
  • Any report about DLL hijacking without demonstrating how it gains new privileges is also out of scope

TL;DR – What We're Looking For

High priority: Vulnerabilities with clear security or business impact, ideally supported by a working proof of concept (PoC)
(e.g. account takeover, data exposure, privilege escalation, financial impact, bypass of security controls)


Lower priority / Informational:

  • Missing best practices or hardening recommendations
  • Theoretical issues without a realistic attack scenario
  • Configuration findings without demonstrable impact

Out of scope:

  • Issues in third-party software
  • Reports affecting only obsolete browsers or unrealistic user behavior
  • Automated scanner findings without manual validation
  • Publicly available or non-sensitive information disclosures

If you're unsure whether an issue is impactful, show us. A short PoC or attack scenario that demonstrates real-world impact significantly increases the likelihood of acceptance and reward.
