Contracts using the cross chain utilies for Arbitrum L2, CrossChainEnabledArbitrumL2 or LibArbitrumL2, will classify direct interactions of externally owned accounts (EOAs) as cross chain calls, even though they are not started on L1. This is assessed as low severity because any action taken by an EOA on the contract could also be taken by the EOA through the bridge if the issue was not present.
This issue has been patched in v4.7.2.
