Tweakers is a Dutch technology website featuring news and information about hardware, software and the Internet. We take security very serious as many of our users use our site as a trusted source. Therefore we have decided to collaborate with ethical hackers that can inform us about potential vulnerabilities in our systems. If you happen to find a vulnerability we'd be more than happy to hear about it and, if its impact is significant enough, award you a bounty as token of appreciation.

  • Please clean up remnants of your testing and do not interfere with the normal operation of the site.
  • Please do NOT use automatic scanners. We cannot accept any submissions found by using automatic scanners.
  • Provide detailed but to-the point reproduction steps
  • Include a clear attack scenario, a step by step guide in the PoC is highly appreciated
  • Suggestions for mitigation are appreciated as well
  • Do not exploit the identified leak: only collect the information necessary to demonstrate its existence.
  • Do not change or delete any data or system settings.
  • Handle any found data in a responsible manner: if you can demonstrate that there is a security problem with a small portion, do not go any further
  • Please do NOT publish/discuss bugs before they are fixed

UPDATE 05-05-2021
Last week we've added 2FA support to Tweakers. Read this article for more information.

UPDATE 07-07-2020
Now possible to search through your Direct Messages (see and use the search bar at the top)

UPDATE 30-04-2020
We added product listings for specific brand and category combinations. For example:

UPDATE 07-04-2020
We've refactored most code in /pricewatch/unsorted/ -> Pricewatch Unsorted

UPDATE 18-02-2020
We've released a new image upload tool in our photo album (account required with enough karma). Uploading multiple images in one go is now possible as well as uploading an image via copy and paste.

UPDATE 04-02-2020
We've created a new interactive Price Graph on our Product pages (For example this product)

UPDATE 21-01-2020
We've released some new features:

ONLY USE YOUR INTIGRITI.ME ADDRESS (in case of violation, no bounty can be awarded)

Please do not use automatic scanners

We're interested to hear about any issue that potentially compromises our company or its user's security. Before submitting a vulnerability make sure to check that it's not listed in our out of scope policy (which you can find below). If you have additional questions about our program feel free to contact us through Intigriti's support.

Please keep the impact on the site as minimal as possible by cleaning up submitted data and not impacting users other than yourself.

Out of scope

ONLY USE YOUR INTIGRITI.ME ADDRESS (in case of violation, no bounty can be awarded)

While we happily welcome any input from researchers that showcase a potential vulnerability in one of our services, we have assembled a list of issues which are out of scope for this program.

Out of scope domain


Known issues

  • Open redirects in privacy consent endpoints (eg /privacygate-confirm, /privacy-wall etc)


  • Pre-auth account takeover / oauth squatting
  • Self-XSS that cannot be used to exploit other users 
  • Verbose messages/files/directory listings without disclosing any sensitive information
  • CORS misconfiguration on non sensitive endpoints
  • Missing cookie flags on non sensitive cookies
  • Missing security headers which do not present an immediate security vulnerability
  • Cross-site Request Forgery with no or low impact
  • Presence of autocomplete attribute on web forms.
  • Reverse tabnabbing
  • Bypassing rate-limits or the non-existence of rate-limits.
  • Best practices violations (password complexity, expiration, re-use, etc.)
  • Clickjacking on pages without sensitive actions
  • CSV Injection
  • Blind SSRF without proven business impact (DNS pingback only is not sufficient)
  • Disclosed and/or misconfigured Google API key (including maps)
  • Host header injection without proven business impact
  • Sessions not being invalidated (logout, enabling 2FA, ..)
  • Hyperlink injection/takeovers
  • Mixed content type issues
  • Cross-domain referer leakage
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection
  • Username / email enumeration
  • E-mail bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks
  • XMLRPC enabled
  • Banner grabbing /Version disclosure
  • Open ports without an accompanying proof-of-concept demonstrating vulnerability
  • Weak SSL configurations and SSL/TLS scan reports
  • Not stripping metadata of images
  • Disclosing API keys without proven impact
  • Bypassing paywall using search services


  • In case that a reported vulnerability was already known to the company from their own tests, it will be flagged as a duplicate.
  • Theoretical security issues with no realistic exploit scenario(s) or attack surfaces, or issues that would require complex end user interactions to be exploited, may be excluded or be lowered in severity
  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks.
  • Vulnerabilities that are limited to non-current browsers (older than 3 versions) will not be accepted
  • Attacks requiring the usage of shared computers, man in the middle or compromised user accounts
  • Attacks requiring unrealistic user interaction
Severity assessment

All our rewards are impact based, therefore we kindly ask you to carefully evaluate a vulnerability's impact when picking a severity rating. To give you an idea of what kind of bugs belong in a certain severity rating we've put some examples below. Note that depending on the impact a bug can sometimes be given a higher/lower severity rating.


  • A remote code execution vulnerability on the production server
  • Full database access (incl. update/delete)


  • A SQL injection vulnerability
  • Access to all customer personal data or access to a targeted user
  • A numeric IDOR that allows mass write/read actions on critical features
  • Path traversal leading to the disclosure of local files


  • Access to random users' data (sensitive PII)
  • A stored XSS vulnerability (excluding unexploitable self-XSS)
  • Vertical authentication bypass


  • A DOM XSS vulnerability
  • Reflected XSS
  • An IDOR leading to the disclosure of non-critical data
  • A CSRF with a significant impact
  • Lateral authentication bypass


  • A reflected XSS vulnerability that requires significant user interaction
  • A CSRF vulnerability in a non-critical feature
  • Open redirect

Cool-down period for zero-days

Recently discovered zero-day vulnerabilities found in in-scope assets within 14 days after the public release of a patch or mitigation may be reported, but are usually not eligible for a bounty. We may however decide to offer a bonus at our own discretion!


Can I receive a test account?
You can register for normal Tweakers-accounts with your email address (max. 3 accounts).
You can find more information regarding addresses here:

Is an English version of the site available?
No, we only offer this site in Dutch but we made sure that our vulnerabilities are in English ;-)

All aboard!
Please log in or sign up on the platform

For obvious reasons we can only allow submissions or applications for our program with a valid Intigriti account.

It will only take 2 minutes to create a new one or even less to log in with an existing account, so don't hesitate and let's get started. We would be thrilled to have you as part of our community.
