Overview

@openzeppelin/contracts-upgradeable is a Secure Smart Contract library for Solidity.

Affected versions of this package are vulnerable to Incorrect Calculation. The ERC721Consecutive contract designed for minting NFTs in batches does not update balances when a batch have size 1 and consists of a single token. Subsequent transfers from the receiver of that token may overflow the balance as reported by balanceOf.
