Ok, at least it has been reported by this 3rd party security focused company. So it's just a matter of time how BSC Beacon chain developer will react to this. If this see this as their fault so they will have to fix it ASAP and who knows, paid the company as a bounty for finding this vulnerabilities.
Unless they ignore it and then let the hackers jump on it.
For sure CZ and his team are looking and yeah that was quick, in less than 24 hours it was patched and that is what to be expected on them.
