Security Policy

Security issues can be reported through our Vulnerability Disclosure Program (VDP). You can report issues via the button below.

 Report issues

Our promise to you

We will respond to report in ultimately one week, probably faster.

We are happy to respond to any questions.

We respect the safe harbour clause as we have with our bug bounty program with integrity.

 

Your promise to us

Provide detailed but to-the point reproduction steps.

Include a clear 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)
