Trick or Treat

Description: The contract does not adequately validate inputs, such as treat names in functions like trickOrTreat and setTreatCost. This can lead to unexpected behavior or errors.

• Found in src/TrickOrTreat.sol Line: 48

  function trickOrTreat(string memory _treatName) public payable nonReentrant {

• Found in src/TrickOrTreat.sol Line: 34

  function setTreatCost(string memory _treatName, uint256 _cost) public onlyOwner {

Impact:

• Invalid or malicious inputs can cause the contract to behave unpredictably or enter an unintended state.

• May allow attackers to exploit the contract by passing unexpected inputs, potentially leading to loss of funds or denial of service.

Proof of Concept:

• Scenario: A user calls trickOrTreat with a non-existent treat name.

• Exploit: The function could proceed with incorrect logic or revert unexpectedly, affecting user experience and contract functionality.

Recommended Mitigation:

• Implement checks to ensure inputs are valid and within expected ranges or formats.

• Use require statements to enforce input constraints and provide informative error messages.

• Conduct thorough testing with edge cases to ensure all inputs are handled correctly.
