- Vulnerabilities that can cause software unavailability, such as App crashes, etc.
- Insecure and irregular code implementations
- Vulnerability messages for third-party libraries
The following are out of scope:
- Anything that isn’t in this repository
- 3rd party library dependencies
- Example code for demonstrating
Please also note that any bugs already reported are considered out of scope.
The severity of reported vulnerabilities will be graded according to CVSS (Common Vulnerability Scoring Standard, https://www.first.org/cvss). The following table will serve as a guideline for reward decisions:
Vulnerability Tier | Reward |
---|---|
Critical (CVSS 9.0 - 10.0) | 5000 - 10000 USDT |
High (CVSS 6.0 - 8.9) | 1000 - 5000 USDT |
Medium (CVSS 4.0 - 5.9) | 500 - 1000 USDT |
Low (CVSS 0.1 - 3.9) | 0 - 500 USDT |
The reward we pay is in Tether USD token on ethereum, so please prepare your ethereum wallet address in advance.
