Take a look at https://github.com/code-423n4/2024-08-wildcat/blob/fe746cc0fbedc4447a981a50e6ba4c95f98b9fe1/src/WildcatArchController.sol#L245-L251
This function is used to register a controller factory, this factory is being used in the window for authorization purposes, issue however is that  ArchController allows for authorizing MarketControllerFactory instances that point to another ArchController.
Otherwise unauthorized actors would be allowed to perform operations i.e. change the protocol fee configuration or deploy controllers.
Consider adding a check in ArchController.registerControllerFactory to make sure that the to-be added MarketControllerFactory is correctly paired with it.
