Summary

Lack of Zero Address Check for _stethBridge in BridgeRouterFacet Constructor

Vulnerability Details

The constructor of the BridgeRouterFacet contract does not check if the _stethBridge parameter is the zero address (0x0).

Impact

If the _stethBridge is set to the zero address, any calls to the stETH bridge will fail, which could disrupt the functionality of the BridgeRouterFacet contract.

Tools Used

Manual Review

Recommendations

Add a check in the constructor to ensure that _stethBridge is not the zero address
