Headline
GHSA-878m-3g6q-594q: OpenZeppelin Contracts contains Incorrect Calculation
Impact
The ERC721Consecutive contract designed for minting NFTs in batches does not update balances when a batch has size 1 and consists of a single token. Subsequent transfers from the receiver of that token may overflow the balance as reported by balanceOf.
The issue exclusively presents with batches of size 1.
Patches
The issue has been patched in 4.8.2.
