PancakeSwap

PancakeSwap is a decentralized exchange running on Binance Smart Chain, with lots of other features that let you earn and win tokens. It's fast, cheap, and anyone can use it. It's also got pancakes and rabbits.

The exchange is an automated market maker (“AMM”) that allows two tokens to be exchanged on the Binance Smart Chain. On top of that, you can earn CAKE with yield farms, earn CAKE with Staking, and earn even more tokens with Syrup pools. Additionally PancakeSwap runs a lottery every 6 hours with 20 000 CAKE injected into the lottery every day.

The PancakeSwap bug bounty program is focused around its smart contracts, websites, and apps with a primary interest in the prevention of loss of user funds, either by direct draining of locked funds or social engineering attacks by redirecting users or forcing them to sign a transaction.

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.

All bug reports must include a Proof of Concept demonstrating how the vulnerability can be exploited to be eligible for a reward. This may be a smart contract itself or a transaction.

The final reward amount for critical smart contract vulnerabilities is capped at 10% of the funds at risk based on the vulnerability reported.

XSS reports are restricted to those that have an impact of prompting a user to sign a transaction or a redirect.

All payouts are done by the PancakeSwap team and are pegged to the USD values set here and are payable in CAKE or BUSD.

All smart contracts excluding lottery-contract and initial-farm-offering.

Issues with the LP contracts that are due to specific underlying tokens are not in scope.

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

Websites and Apps

• Remote Code Execution
• Trusting trust/dependency vulnerabilities
• Vertical Privilege Escalation
• XML External Entities Injection
• Horizontal Privilege Escalation
• Stored XSS
• Reflective XSS with impact
• CSRF (reports of CSRF must include a demonstration of impact)
• Direct object reference
• Session fixation
• Insecure Deserialization
• Direct object reference
• DOM XSS

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)

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

Websites and Apps

• 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
• Feature requests
• Best practices
• Internal SSRF
• Path Traversal
• SPF/DKIM/DMARC Configuration Problems
• SSL misconfigurations
• SSL/TLS issues (weak crypto, improper setup)
• Clickjacking
• Misleading Unicode text (e.g. using right to left override characters)
• HTTP security headers
• Cache control issues

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
