Impacts in Scope

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

These accepted impacts are then based on the severity classification system of this bug bounty program. When submitting a bug report, please select the severity level you feel best corresponds to the severity classification system as long as the impact itself is one of the listed items.

If an impact can be caused to any other asset managed by Immunefi that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for consideration by Immunefi.

Critical
Execute arbitrary system commands
Critical
Retrieve sensitive data/files from a running server such as: database passwords,blockchain keys, etc (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
Critical
Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield
Critical
Permanent freezing of funds
High
Injecting/modifying the static content on the target application without Javascript (Persistent) such as: HTML injection without Javascript, replacing existing text with arbitrary text, arbitrary file uploads, etc
High
Changing sensitive details of other users (including modifying browser local storage) without already-connected wallet interaction and with up to one click of user interaction, such as: email or password of the victim, etc
High
Improperly disclosing confidential user information such as: email address, phone number, physical address, etc

Out of scope

Program's Out of Scope information

These impacts are excluded from the rewards for this bug bounty program.

All Categories

  • Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
  • Impacts caused by attacks requiring hypothetical access to leaked keys/credentials
  • Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
  • 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

Smart Contracts

  • 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

Web/App

  • 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

The following activities are prohibited by this bug bounty program:

  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • 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 that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules.
