Description:

According to the Steaking Docs. The role of the steak protocol team multisig who is basically the owner of the steaking contract are only responsible for setting the vault address after the staking period ends. But then in the stake function it does not restrict the owner from staking ETH.

Impact:

The owner can potentially stake ETH, which could lead to conflicts of interest or unintended manipulation of the staking process, affecting the fairness and transparency of the protocol.

Recommended Mitigation:

Add a check in the stake function to ensure that the owner cannot stake ETH. This can be done by asserting that msg.sender is not the owner before proceeding with the staking logic.
