As far as I know, the third-party cookies are used as part of the single login implementation – for example, when you log in on *, we attempt to also set cookies for *, * and so on, to log you in on those sites as well. Unfortunately, Wikimedia sites are spread across multiple domains, which browsers consider to be "third parties" to each other.

If you're blocking third-party cookies, that just means you'll have to log in on each project separately. It shouldn't cause any problems. If you want to get rid of the warning, it might be possible to configure your browser to allow third-party cookies on Wikimedia sites.

There is a public bug report about these issues: T257803: Chrome's "Block third-party cookies" option breaks CentralAuth edge login / autologin.

I don't see a security issue here per definition, so I'm making this ticket public.

Aklapper changed the visibility from "Custom Policy" to "Public (No Login Required)".
Aklapper changed the edit policy from "Custom Policy" to "All Users".

...but Phab does not let my user account change the task subtype. Sigh.
