Critical
Permanent freezing of funds
Critical
Economic attacks against the protocol
Critical
Execute arbitrary system commands
Critical
Retrieve sensitive data/files from a running server such as /etc/shadow, database passwords, and blockchain keys(this does not include non-sensitive environment variables, open source code, or usernames)
Critical
Taking down the application/website
Critical
Taking state-modifying authenticated actions (with or without blockchain state interaction) on behalf of other users without any interaction by that user, such as, changing registration information, commenting, voting, making trades, withdrawals, etc.
Critical
Subdomain takeover with already-connected wallet interaction
Critical
Direct theft of user funds
Critical
Malicious interactions with an already-connected wallet such as modifying transaction arguments or parameters, substituting contract addresses, submitting malicious transactions
High
Theft of unclaimed yield

Out of scope

Program's Out of Scope information

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks requiring access to leaked keys/credentials
  • Attacks requiring access to privileged addresses (governance, strategist)
  • 3rd party services (AWS, Datadog, etc)

Smart Contracts and Blockchain

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Basic economic governance attacks (e.g. 51% attack)
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks
  • Centralization risks
  • 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

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Captcha bypass using OCR
  • CSRF with no security impact (logout CSRF, change language, etc.)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
  • Server-side information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring unlikely user actions
  • URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Attacks requiring privileged access from within the organization
  • Feature requests
  • Best practices

The following activities are prohibited by this bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic https://app.contentful.com/spaces/t3wqy70tc3bv/entries/6ma3iB5ROn10dgV8XvvvAU - Public disclosure of an unpatched vulnerability in an embargoed bounty
