Summary

Use of unlocked pragma

Vulnerability Details

The 3 contracts use an unlocked pragma (pragma solidity ^0.8.18;) which is not fixed to a specific Solidity version. Locking the pragma helps ensure that contracts do not accidentally get deployed using a different compiler version with which they have been tested the most.

Recommendations

Lock pragmas to a specific Solidity version. It is also recommended to use the latest version of Solidity when deploying contracts (see Solidity docs).
