ERC1155Supply vulnerability in OpenZeppelin Contracts
When ERC1155 tokens are minted, a callback is invoked on the receiver of those tokens, as required by the spec. When including the ERC1155Supply extension, total supply is not updated until after the callback, thus during the callback the reported total supply is lower than the real number of tokens in circulation.
Impact
If a system relies on accurately reported supply, an attacker may be able to mint tokens and invoke that system after receiving the token balance but before the supply is updated.
Patches
A fix is included in version 4.3.3 of @openzeppelin/contracts and @openzeppelin/contracts-upgradeable.
Workarounds
If accurate supply is relevant, do not mint tokens to untrusted receivers.
