This contract inherits from OpenZeppelins library and the transferOwnership() function is the default one (a one-step process). Its possible that the onlyOwner role mistakenly transfers ownership to a wrong address, resulting in a loss of the onlyOwner role (which is quite powerful given the power from L274:function call). Consider overriding the default transferOwnership() function to first nominate an address as the pending owner and implementing an acceptOwnership() function which is called by the pending owner to confirm the transfer.
