Use abi.encode() instead which will pad items to 32 bytes, which will prevent hash collisions (e.g. abi.encodePacked(0x123,0x456) => 0x123456 => abi.encodePacked(0x1,0x23456), but abi.encode(0x123,0x456) => 0x0...1230...456). Unless there is a compelling reason, abi.encode should be preferred. If there is only one argument to abi.encodePacked() it can often be cast to bytes() or bytes32() instead.
If all arguments are strings and or bytes, bytes.concat() should be used instead.
