Report a Vulnerability Download PGP Key

At WebSec, we consider the security of our systems a top priority. But no matter how much effort we put into system security, there can still be vulnerabilities present.

While our systems undergo pentests on a regular basis we are very courious if the community out there can still find security issues within our web applications. So if you are a security researcher / ethical hacker and you discover a vulnerability than we would like to know about it so we can take steps to address it as quickly as possible and learn to improve our services from your findings.

What we ask you

  1. Please click the "Submit a Vulnerability" button to send us your findings or if this doesn't work then please Encrypt your findings using our PGP Key and e-mail it to us at security@websec.nl to prevent this critical information from falling into the wrong hands.
  2. Do not take advantage of the vulnerability or problem you have discovered, for example by downloading more data than necessary to demonstrate the vulnerability or deleting or modifying other people's data.
  3. Do not reveal the problem to others until it has been resolved.
  4. Do not attemt any physical, (distributed) denial of service or non-relevant spam attacks, and always provide sufficient information to reproduce the problem, so that we will be able to resolve it as quickly as possible. Usually, the IP address or the URL of the affected system and a description of the vulnerability will be sufficient, but complex vulnerabilities may require further explanation.
  5. Do not publish your findings without our consent, we would like to be involved in any publication involving our security.
  6. Respect our Triage Agents, we reserve the right to reject further communication and rewards at all times, specifically when our agents feel threatned / intimidated or uncomfortable. In such cases we can also block the researcher from any further participation in our vulnerability disclosure program.

  2. If you have followed the instructions above, we will not take any legal action against you in regard to the report,
  3. We will handle your report with strict confidentiality, and not pass on your personal details to third parties without your permission,

  5. For valid repots we will post your name on our website (unless you desire otherwise), and as a token of our gratitude for your assistance, we offer a reward for every valid report of a security problem that was not yet known to us which has a CVSSv3.1 score of 4.0 or higher.

The type of reward depends on the Report Quality, Validity, Impact and Exploitability we will measure which reward is appropriate for your finding. A reward can be of the following type: Hall of Fame listing, Swag Pack, Formal letter of Recognition & Appreciation, Steam or Origin CD Keys and in some cases a Financial Reward.
