vulnerability test

Hello,

This has been a while ago, but I was using Opera VPN at the time and Bitdefender.

I did a vulnerability test and it showed a message that Opera had some security? issues and people could potentially access things on my computer. At the time I didnt think much of it and just pressed fix. However I'm not sure how long this privacy issue was and I'm not sure if someone had access to my PC at the time. So I have a few questions regarding this if possible.

1. Is it common for Bitdefender to see security issues in Opera VPN
2. If someone did try to access my PC through Opera VPN, would Bitdefender have detected that
