Are M365 Defender alerts for CVE-2020-0601 something to worry about?

Hey everyone! I'm still pretty new to security stuff and I've been tasked with managing it at my medium-sized company with around 200 people. Today, I spotted two alerts in the M365 Defender portal indicating attempts to exploit CVE-2020-0601 — one was from March and the other just popped up on my own PC. Both alerts refer to a Microsoft root certificate with its SHA1 hash. After doing a bit of research, I learned that this issue is linked to certificate spoofing, but it seems to have been patched back in 2020 through Windows Update. I'm a bit confused about how serious these alerts are and what steps I should take next. Should I be worried about them happening more than once, especially on my own machine? Any insights or advice would be greatly appreciated!
