Responsible Disclosure Program

Application

• 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
• Missing security headers
• 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 with no sensitive actions
• CSV Injection
• Host header injection without proven business impact
• Blind SSRF without proven business impact (DNS pingback only is not sufficient)
• Disclosed and/or misconfigured Google API key (including maps)
• 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 credentials without proven impact
• Disclosing API keys without proven impact
• Same-site scripting
• Subdomain takeover without taken over the subdomain
• Arbitrary file upload without proof of the existence of the uploaded file

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 physical access to a victim’s computer/device, 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.
• Reports that state that software is out of date/vulnerable without a proof-of-concept
• Access to a neighbourhood with someone else's address and using the regular "Find my neighbourhood" flow on the website or in the app

Mobile

• Shared links leaked through the system clipboard
• Any URIs leaked because a malicious app has permission to view URIs opened
• The absence of certificate pinning
• Sensitive data in URLs/request bodies when protected by TLS
• Lack of obfuscation
• Path disclosure in the binary
• Lack of jailbreak & root detection
• Crashes due to malformed URL Schemes
• Lack of binary protection (anti-debugging) controls, mobile SSL pinning
• Snapshot/Pasteboard leakage
• Runtime hacking exploits (exploits only possible in a jailbroken environment)
• API key leakage used for insensitive activities/actions
• Attacks requiring physical access to the victim's device
• Attacks requiring installing malicious applications onto the victim's device
