upgrade function is not protected

Summary

upgrade function is not protected

Vulnerability Details

function upgrade(
RootProxy.BranchUpgrade[] memory branchUpgrades,
address[] memory initializables,
bytes[] memory initializePayloads
)
external
{
_authorizeUpgrade(branchUpgrades);
RootUpgrade.Data storage rootUpgrade = RootUpgrade.load();
​
​
rootUpgrade.upgrade(branchUpgrades, initializables, initializePayloads);
}

The upgrade function calls _authorizeUpgrade, which is marked with the onlyOwner modifier, the upgrade function itself is not restricted. This means that anyone can call the upgrade function, and only the internal _authorizeUpgrade check is protected.

This is problematic because:

  1. It allows non-owners to initiate the upgrade process, even though they shouldn't be able to pass the authorization check.

  2. It may lead to unnecessary gas consumption as non-owners can cause the contract to execute part of the upgrade logic before reverting.

  3. It could potentially be exploited if there's any side effect in the code before the _authorizeUpgrade check.

The _authorizeUpgrade function is empty, which means it doesn't actually perform any checks on the branchUpgrades parameter.

Impact

It may lead to unnecessary gas consumption as non-owners can cause the contract to execute part of the upgrade logic before reverting.

Tools Used

Manual Review

Recommendations

The upgrade function should also be restricted to the owner
