The original issue was already public and the fix is also available upstream: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/420784e342da4883f6debdfe10cde68507b10d27 therefore it seems to late to keep the issue non public.

I absolutely agree and not sure why it was embargoed. We'll sort it out today.
