Description: Description: When adding a new module to the orchestrator, the system does not check whether a module with the same title already exists. This can lead to duplicate module titles, which can result in incorrect values being returned by the _isModuleUsedInOrchestrator function.

Scenario: If two modules with the same title are added, the findModuleAddressInOrchestrator function will be unable to differentiate between them. This can cause the function to return the wrong module address.

Impact: The incorrect module address returned by findModuleAddressInOrchestrator can lead to various issues, including the execution of unintended modules, potential security vulnerabilities, and unexpected behavior of the system.

Mitigation: Implement a check for duplicate module titles when adding new modules to ensure that each module has a unique title. This will prevent the addition of modules with duplicate titles and ensure the correct functioning of findModuleAddressInOrchestrator.

Another scenario:

• there is a module with title x and major version 1 and URL y
• admin add new module with title x and URL z or major version 2 (URL or version changed)
• the title is the same
• user add this new module

Other Mitigation:

Instead of title, use identifier.

Titles could be the same, but identifiers not.

    function identifier(IModule_v1.Metadata memory metadata)
        internal
        pure
        returns (bytes32)
    {
        return keccak256(
            abi.encode(metadata.majorVersion, metadata.url, metadata.title)
        );
    }

Yes youre correct here. It seems we forgot to add the disclaimer in the natspec, as we knew of that interactions. I would consider this low though as the function is basically not used anywhere.
