Summary

The ContestManager and Pot contracts use a floating pragma (^0.8.20), which could lead to issues if future Solidity compiler versions introduce changes or bugs.

Vulnerability Details

Both contracts specify a floating version for the Solidity compiler (^0.8.20). While this allows flexibility in using newer compiler versions, it also introduces the risk of unforeseen changes or bugs in future versions, which could affect the contracts' behavior.

Impact

Using a floating pragma can result in unexpected behavior due to compiler updates, potentially introducing bugs or inconsistencies in contract functionality.

Tools Used

Manual code review.

Recommendations

Lock the pragma to a specific compiler version, such as pragma solidity 0.8.20, to ensure consistent behavior across deployments.
