Take a look at https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/contracts/ethereum/contracts/governance/Governance.sol#L168-L202
These function at the long run call the below: https://github.com/code-423n4/2024-03-zksync/blob/4f0ba34f34a864c354c7e8c47643ed8f4a250e13/code/contracts/ethereum/contracts/governance/Governance.sol#L225-L235
These functions are used to execute schedule operations either instantly or after their respective delays have passed, now issue is that the public function are marked as payable which suggests that while calling these functions, msg.value is going to be passed with them, but in the internal _execute() there is no validation that the msg.value provided is equal to the total value of call[i].value needed in the loop.
Potential having excess funds in the Governance.sol, i.e when the msg.value is way greater than the total call.value needed for the transaction, or not enough funds being available for the execution which then leads to eating up funds that have been sent to the contract for different operations
Check that msg.value == the total call value needed, if protocol plans on routing the logic via the balance too, then check if the msg.value + contract's balance of eth is enough for transaction.
