Out-of-scope vulnerabilities

  • Very recently (60 days) disclosed 0-day vulnerabilities since we need to patch our systems.
  • Missing security headers that are recommended but do not present an immediate security vulnerability.
  • Best practice suggestions including but not limited to:
    • Password strength (weak password policy)
    • Rate limiting configurations (missing or low rates unless it can potentially affect the system/business)
    • IDOR (non-sensitive information disclosure)
  • Using Instamojo server to DDoS some external systems.
  • Self-XSS that can not be used to exploit other users (this includes having a user paste JavaScript into the browser console).
  • Frontend price manipulation without a successful transaction.
  • API response manipulation tricks the UI but does not affect the server state.


Bounty reward

All valid bugs are awarded a bounty based on their impact. The exact amount of bounty to be given out will be at the discretion of Instamojo. The reward will be remitted to Indian bank accounts via NEFT. We are not currently able to make international remittances at this time.
