In general, the following vulnerabilities do not correspond to the severity threshold: Vulnerabilities in third-party applications Assets that do not belong to the company Clickjacking on pages with no sensitive actions Best practices concerns Recently (less than 30 days) disclosed 0day vulnerabilities Vulnerabilities affecting users of outdated browsers or platforms Social engineering, phishing, physical, or other fraud activities Publicly accessible login panels without proof of exploitation Reports that state that software is out of date/vulnerable without a proof of concept Reports generated by scanners or any automated or active exploit tools Vulnerabilities involving active content such as web browser add-ons Most brute-forcing issues without clear impact Denial of service (DoS/DDoS) Theoretical issues Moderately Sensitive Information Disclosure Spam (sms, email, etc) Missing HTTP security headers CORS related issues unless you can exfiltrate data. Infrastructure vulnerabilities, including: Certificates/TLS/SSL-related issues; DNS issues (i.e. MX records, SPF records, DMARC records etc.); Server configuration issues (i.e., open ports, TLS, etc.) Open redirect - unless an additional security impact can be demonstrated Session fixation User account enumeration Clickjacking/Tapjacking and issues only exploitable through clickjacking/tapjacking Descriptive error messages (e.g. Stack Traces, application or server errors) Self-XSS that cannot be used to exploit other users Login & Logout CSRF Weak Captcha/Captcha Bypass Lack of Secure and HTTPOnly cookie flags Username/email enumeration via Login/Forgot Password Page error messages CSRF in forms that are available to anonymous users (e.g. the contact form) OPTIONS/TRACE HTTP method enabled Host header issues without proof-of-concept demonstrating clear security impact Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS Content Spoofing without embedded links/HTML Reflected File Download (RFD) Mixed HTTP Content HTTPS Mixed Content Scripts Manipulation with Password Reset Token MitM and local attacks Leakage of non sensitive API keys (e.g. Etherscan, Infura, Alchemy, etc.) Any vulnerability exploit requiring browser bugs for exploitation (e.g. CSP bypass) UI/UX best practice recommendations Automated scanner reports without demonstrated impact Comma Separated Values (CSV) injection without demonstrating a vulnerability. Response manipulations without demonstration of system state change Program Rules Avoid using web application scanners for automatic vulnerability searching which generates massive traffic You must be at least 18 years old. Make every effort not to damage or restrict the availability of products, services, or infrastructure Avoid compromising any personal data, interruption, or degradation of any service Don’t access or modify other user data, localize all tests to your accounts Perform testing only within the scope Don’t exploit any DoS/DDoS vulnerabilities, social engineering attacks, or spam Don’t spam forms or account creation flows using automated scanners In case you find chain vulnerabilities we’ll pay only for vulnerability with the highest severity.
