Submission Details
Severity:
Missing Zero-Address Validation
Description: The contract assigns values to address state variables without checking for the zero address (0x0).
host = _newHost;
Impact:
Potential assignment of invalid addresses
Risk of function calls to zero address
Possible loss of contract control
Recommended Mitigation: Add zero-address validation before address assignments:
function changeHost(address _newHost) external onlyHost {
require(_newHost != address(0), "Invalid zero address");
if(!participant[_newHost]) {
revert OnlyParticipantsCanBeHost();
}
host = _newHost;
emit NewHost(host);
}
