Default Out of Scope and rules

Web & App specific

  • Theoretical impacts without any proof or demonstration
  • Impacts involving attacks requiring physical access to the victim device
  • Impacts involving attacks requiring access to the local network of the victim
  • Reflected plain text injection (e.g. url parameters, path, etc.)
    • This does not exclude reflected HTML injection with or without JavaScript
    • This does not exclude persistent plain text injection
  • Any impacts involving self-XSS
  • Captcha bypass using OCR without impact demonstration
  • CSRF with no state modifying security impact (e.g. logout CSRF)
  • Impacts related to missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
  • Server-side non-confidential information disclosure, such as IPs, server names, and most stack traces
  • Impacts causing only the enumeration or confirmation of the existence of users or tenants
  • Impacts caused by vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
  • Lack of SSL/TLS best practices
  • Impacts that only require DDoS
  • UX and UI impacts that do not materially disrupt use of the platform
  • Impacts primarily caused by browser/plugin defects
  • Leakage of non sensitive API keys (e.g. Etherscan, Infura, Alchemy, etc.)
  • Any vulnerability exploit requiring browser bugs for exploitation (e.g. CSP bypass)
  • SPF/DMARC misconfigured records)
  • Missing HTTP Headers without demonstrated impact
  • Automated scanner reports without demonstrated impact
  • UI/UX best practice recommendations
  • Non-future-proof NFT rendering

All categories

  • Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
  • Impacts caused by attacks requiring access to leaked keys/credentials
  • Impacts caused by attacks requiring access to privileged addresses (including, but not limited to: governance and strategist contracts) without additional modifications to the privileges attributed
  • Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
  • Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
  • Best practice recommendations
  • Feature requests
  • Impacts on test files and configuration files unless stated otherwise in the bug bounty program
  • Impacts requiring phishing or other social engineering attacks against project's employees and/or customers
