That video ended the embargo. If someone releases a video telling you how to run an embargoed exploit, it's not an embargoed exploit any longer.
The embargo was announced for Oct 21 14:00 UTC: https://www.php.net/archive/2026.php#2026-10-20-1
The video was posted 44 seconds before that time: https://x.com/lcfr_hax/status/2112906567662399830
This can't possibly be interpreted as some major violation of the embargo, so what are people talking about?
That's not how embargos work.
