Out of scope

Program's Out of Scope information
  • 3rd party services (AWS, Datadog, etc)

  • All issues reported in past audits are out of scope https://docs.moonwell.fi/moonwell/protocol-information/audits

  • No bounties will be paid for issues that arise from a governor turning malicious. Instead, the researcher must demonstrate how the code is vulnerable without using known issues and provide a working PoC of the exploit to demonstrate this vulnerability.

  • Known issues are out of scope, such as double voting assuming block timestamps between chains drift far enough apart

Default Out of Scope and rules

Smart Contract specific

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Impacts requiring basic economic and governance attacks (e.g. 51% attack)
  • Lack of liquidity impacts
  • Impacts from Sybil attacks
  • Impacts involving centralization risks

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
