`CharityRegistry::isVerified` incorrectly mofidies `registeredCharities` instead of `verifiedCharities`, making unverified charities can receive donations

nap23

Summary

The isVerified function in CharityRegistry contract modifies the registeredCharities mapping instead of the verifiedCharities mapping. This allows unverified charities to receive donations.

Vulnerability Details

function isVerified(address charity) public view returns (bool) {
@> return registeredCharities[charity];
}

Impact

The logic of the contract is incorrect. The isVerified function should return whether the charity is verified or not. However, it returns whether the charity is registered or not. This allows unverified charities to receive donations.

Recommendations

function isVerified(address charity) public view returns (bool) {
return verifiedCharities[charity];
}
