Program Overview

Fuse was founded in 2019 with a mission to bring the power of mobile payments to communities around the world. With Fuse, anyone can launch and manage these new networks, empowered by simple, easy to use tools. A highly-skilled, diverse team of blockchain and web–based technology experts has been assembled in order to execute on our ambitious vision of putting truly democratized and borderless money into the hands of millions.

The bug bounty program is focused around its smart contracts used in its products, namely FuseSwap and FuseRewards, and is mostly concerned with the loss of user funds.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

Payouts are handled by Fuse directly and are denominated in USD. However, payouts are done in FUSE.

One issue we know of with WFUSE is that totalSupply is not working. So, all vulnerabilities related to that are not given a reward, as it is a known issue.

Prioritized Vulnerabilities

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts/Blockchain:

  • Re-entrancy
  • Logic errors
    • including user authentication errors
  • Solidity/EVM details not considered
    • including integer over-/under-flow
    • including unhandled exceptions
  • Trusting trust/dependency vulnerabilities
    • including composability vulnerabilities
  • Oracle failure/manipulation
  • Novel governance attacks
  • Economic/financial attacks
    • including flash loan attacks
  • Congestion and scalability
    • including running out of gas
    • including block stuffing
    • including susceptibility to frontrunning
  • Consensus failures
  • Cryptography problems
    • Signature malleability
    • Susceptibility to replay attacks
    • Weak randomness
    • Weak encryption
  • Susceptibility to block timestamp manipulation
  • Missing access controls / unprotected internal or debugging interfaces

Web/App Vulnerabilities

We accept the following website/app vulnerabilities, though there is no reward for them:

  • Remote Code Execution
  • Trusting trust/dependency vulnerabilities
  • Vertical Privilege Escalation
  • XML External Entities Injection
  • SQL Injection
  • LFI/RFI
  • Horizontal Privilege Escalation
  • Stored XSS
  • Reflective XSS with impact
  • CSRF
  • CSRF with impact
  • Direct object reference
  • Internal SSRF
  • Session fixation
  • Insecure Deserialization
  • Direct object reference
  • Path Traversal
  • DOM XSS
  • SSL misconfigurations
  • SSL/TLS issues (weak crypto, improper setup)
  • URL redirect
  • Clickjacking
  • Misleading Unicode text (e.g. using right to left override characters)
  • Coercing the application to display/return specific text to other users

Out of Scope & Rules

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)
  • 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

The following vulnerabilities are not sought after for website bug reports:

  • Theoretical vulnerabilities without any proof or demonstration
  • Content spoofing / Text injection issues
  • Self-XSS
  • 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

The following activities are prohibited by 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
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
