Note those dates are DAY-MONTH. At least they patched it within a single day.
I find it funny that the author found a massive vulnerability but chose to wait a couple days to report it so they could finish a nice write-up.
Reminds me of my experience with HackerOne: We had some participants who would find a small vulnerability, but then sit on it for months while they tried to find a way to turn it into a larger vulnerability to claim a higher prize.
Then when they finally gave up on further escalation and submitted it, they'd get angry when we informed them that we had already patched it (and therefore would not pay them). The incentives in infosec are weird.
