Описание
OpenZeppelin Contracts and Contracts Upgradeable duplicated execution of subcalls in v4.9.4
Context
Merge conflict resolution issue when porting the v5.0.1 Multicall update to the v4.9 branch caused a duplicated line.
Impact
Versions using Multicall from @openzeppelin/contracts@4.9.4 and @openzeppelin/contracts-upgradeable@4.9.4 will execute each subcall twice. Concretely, this exposes a user to unintentionally duplicate operations like asset transfers.
Patches
The duplicated delegatecall was removed in 4.9.5. The 4.9.4 version is marked as deprecated.

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.
