Our promise to you

  • We will respond to report in ultimately two weeks, probably faster!
  • We are happy to respond to any questions, please use the button in the right top corner for this.
  • We respect the safe harbour clause that you can find below

Your promise to us

  • Provide detailed but to-the point reproduction steps
  • Include a clear attack scenario. How will this affect us exactly?
  • Remember: quality over quantity!
  • Please do not discuss or post vulnerabilities without our consent (including PoC's on YouTube and Vimeo)
  • Please do not use automatic scanners -be creative and do it yourself! We cannot accept any submissions found by using automatic scanners. Scanners also won't improve your skills, and can cause a high server load (we'd like to put our time in thanking researchers rather than blocking their IP's 😉)

In scope

IMPORTANT:

The websites partially share the same codebase with other DPG products (included, but not limited to, Algemeen Dagblad, De Morgen, De Volkskrant, Het Parool, Humo, Trouw). They can contain common issues. If a specific issue has already been found in another DPG website it will be treated as a duplicate.

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.

General

  • 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
  • Recently disclosed zero-day vulnerabilities in commercial products where no patch or a recent patch (< 2 weeks) is available. We need time to patch our systems just like everyone else - please give us 2 weeks before reporting these types of issues.
  • 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.

Exceptional

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

Critical

  • 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

High

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

Medium

  • 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

Low

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