NodeRegistry.registerNodeFor() no replay protection and expiration  Won't Fix
An owner can register a node with the signer not being the owner by calling `registerNodeFor`. The owner submits a message signed for the owner including the properties of the node including the url.\\nThe signed data does not include the `registryID` nor the NodeRegistry's address and can therefore be used by the owner to submit the same node to multiple registries or chains without the signers consent.\\nThe signed data does not expire and can be re-used by the owner indefinitely to submit the same node again to future contracts or the same contract after the node has been removed.\\nArguments are not validated in the external function (also see issue 6.17)\\n```\\nbytes32 tempHash = keccak256(\\n    abi.encodePacked(\\n        \\_url,\\n        \\_props,\\n        \\_timeout,\\n        \\_weight,\\n        msg.sender\\n    )\\n);\\n```\\n
Include `registryID` and an expiration timestamp that is checked in the contract with the signed data. Validate function arguments.
