[Security] Please enable private vulnerability reporting

[sungmw]

Hi,

I found a security vulnerability in
go-drive related to missing frame
protection headers (CWE-1021).

I have a detailed report with PoC ready,
but I'd like to share it privately.

Could you please either:

1. Enable "Private vulnerability
   reporting" in repo Settings > Code
   security and analysis
2. Or provide a contact email for security
   reports?

Thank you.
