A researcher found a vulnerability in the French government WhatsApp replacement app: Tchap. The vulnerability allows anyone to surreptitiously join any conversation.

Of course the developers will fix this vulnerability. But it is amusing to point out that this is exactly the backdoor that GCHQ is proposing.
