As it presently is constructed, the contract is vulnerable to the [allowance double-spend exploit](https://github.com/OpenZeppelin/openzeppelin-solidity/blob/b4f87bb8fc25fb07f73099701e39e167a3d36465/contracts/token/ERC20/ERC20.sol#L71-L78), as with other ERC20 tokens.
Open the reportThe clone-and-own approach involves copying and adjusting open source code at one's own discretion. From the development perspective, it is initially beneficial as it reduces the amount of effort. However, from the security perspective, it involves some risks as the code may not follow the best practices, may contain a security vulnerability, or may include intentionally or unintentionally modified upstream libraries. Rather than the clone-and-own approach, a good industry practice is to use the Truffle framework for managing library dependencies. This eliminates the clone-and-own risks yet allows for following best practices, such as, using libraries.
