Yes, absolutely. And the common element here strongly points at Lovable setting things up in such a way that this kind of vulnerability can easily be the result of using their product. I really don't buy their position that they have no responsibility here, as far as I can see Supabase, Lovable and the customers of Lovable all failed to do right by the data subjects. Every one of those websites whose data was downloaded effectively has a reportable breach on their hands and Lovable and Supabase have one as well.

If they wipe this under the carpet the lot of them could be in really hot water if a regulator finds out. I tried asking the CISO of Lovable up-thread about this but they never answered, and I really think those questions need to be answered, and need to be answered publicly.

> It's not breach for the researcher. The researcher(s) themselves need legal basis to obtain this information which would likely be "legitimate interest" and then follow the other principals of GDPR (like deleting the data when no longer needed).

Good luck arguing that you had legitimate interest in data of people who did not consent to you having it in the first place.

The GDPR does not have a 'legitimate interest' category that includes exploiting breaches. White hat hackers are neither processors nor controllers and can never claim legitimate interest in the data.
