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
