Liquid Staking

Summary

The _authorizeUpgrade function in Vault and OperatorVault uses the onlyOwner modifier, but there is no explicit mention or documentation of the upgrade functions or mechanisms in the contract code provided. This inconsistency can lead to confusion or misconfiguration regarding who is authorized to perform upgrades.

Vulnerability Details

In Vault.sol:

Similarly in OperatorVault.sol. While the function restricts upgrades to the contract owner, the lack of documentation and clarity on the upgrade process can cause confusion.

Impact

• Potential Unauthorized Upgrades: If ownership is not correctly managed, an attacker could perform unauthorized upgrades.

• Operational Confusion: Developers and operators may be unsure of the correct upgrade procedures.

Tools Used

Manual code review.

Recommendations

• Document Upgrade Mechanism:

  • Provide clear documentation on how upgrades are performed.

  • Explain who the owner is and how ownership can be transferred.

• Ownership Management:

  • Ensure that ownership is securely managed, possibly using a multi-signature wallet.

• Event Emission:

  • Emit events when upgrades are authorized or performed to enhance transparency.
