Submission Details
Severity:
The implementation address has not been verified for the null address (address(0)).
Summary
To mitigate potential risks of unexpected behaviors, it is crucial to validate critical constructor inputs that are addresses against address(0). Currently, there is a lack of address(0) validation for the address input in the following constructor:
constructor(address implementation) {
_implementation = implementation;
}
Impact
The _implementation address has the potential to be designated as address(0).
Tools Used
Manual code review
Recommendations
Please incorporate a verification checkpoint to ensure that the null address (0x0) is not accepted.
