Owner can renounce ownership
OpenZeppelin's renounceOwnership is exposed without a guard, so an accidental or unauthorized call leaves the contract permanently ownerless and breaks 16 admin paths.
Description
Typically, the contract's owner is the account that deploys the contract. As a result, the owner is able to perform certain privileged activities.
The OpenZeppelin's Ownable used in this project contract implements renounceOwnership. This can represent a certain risk if the ownership is renounced for any other reason than by design.
Impact
Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner. In this codebase there are 16 functions that would be affected in such scenario.
Recommendation
It's recommended that the Owner is not able to call renounceOwnership without transferring the Ownership to other address before.
In addition, if a multi-signature wallet is used, calling renounceOwnership function should be confirmed for two or more users.
