In scope


Welcome to our program! We understand that no technology is perfect and we're grateful for the work of our security researchers and community members in identifying any vulnerabilities. Your efforts help us ensure the security and privacy of our users.

Since this is a vulnerability disclosure program and not a bug bounty program, we don't have financial rewards for your findings. However, we believe in the value of community and the power of collective problem-solving and appreciate your efforts to maintain the integrity and security of our platforms.

Our worst-case scenarios are:

  • Breach of personal data of our customers
  • Breach of data stored by our customers in our service
  • Abuse of our APIs creating denial of service in a manner which we cannot easily filter/block (eg. ransoming us against service unavailability)

Out of scope

About known issues

Due to the nature of the VDP, we are not able to provide you a complete list of known issues at the moment.

List of things out of scope:


  • Any domain that is not listed in the Domains section, is out of scope for this program


  • API key disclosure without proven business impact
  • Bypassing Cloudflare
  • Pre-Auth Account takeover/OAuth squatting
  • Self-XSS that can't 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
  • Sessions not being invalidated (logout, enabling 2FA, etc.)
  • Hyperlink injection/takeovers
  • Mixed content type issues
  • Cross-domain referrer leakage
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection
  • Username/email enumeration
  • Email 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 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
  • Blind SSRF without proven business impact (DNS pingback only is not sufficient)
  • Disclosed and/or misconfigured Google API key (including maps)
  • Host header injection without proven business impact


  • In case that a reported vulnerability was already known to the company from their own tests, it will be flagged as a duplicate. Please look also at the issues we're working with.
  • 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 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
  • Reports that state that software is out of date/vulnerable without a proof-of-concept
