CVE-2023-49798
CVE-2023-49798 · Duplicated execution of subcalls in OpenZeppelin Contracts
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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/[email protected]` and `@openzeppelin/[email protected]`, 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.
