Summary
Duplicated execution of subcalls in OpenZeppelin Contracts
Details

OpenZeppelin Contracts is a library for smart contract development. A merge issue when porting the 5.0.1 patch to the 4.9 branch caused a line duplication. In the version of Multicall.sol released in @openzeppelin/contracts@4.9.4 and @openzeppelin/contracts-upgradeable@4.9.4, all subcalls are executed twice. Concretely, this exposes a user to unintentionally duplicate operations like asset transfers. The duplicated delegatecall was removed in version 4.9.5. The 4.9.4 version is marked as deprecated. Users are advised to upgrade. There are no known workarounds for this issue.
