For those running Mac OS 10.15, do you see an update? I’ve been running 10.15.6 for awhile and I don’t see any update for that.
The bug may not be in 10.15 or maybe they’ll release a security fix for it shortly. I’d be surprised if they leave it unpatched; Apple usually supports two versions back with security fixes.
Catalina Security Update 2021-005 (MacOS 10.15.7 build 19H1417) was released on Sept. 13.
