Our promise to you

• 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 😉)

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

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!
