Is your feature request related to a problem? Please describe.

When going through the Best Practices followed for OpenSource Projects on : https://www.bestpractices.dev/en/projects/8099

I found this .

If private vulnerability reports are supported, the project MUST include how to send the information in a way that is kept private. (URL required)

Examples include a private defect report submitted on the web using HTTPS (TLS) or an email encrypted using OpenPGP. If vulnerability reports are always public (so there are never private vulnerability reports), choose "not applicable" (N/A).

Describe the solution you'd like
Private Defect Report via Web:

Provide a URL for submitting vulnerability reports via a secure web form. Create a secure web form for submitting vulnerability reports using HTTPS.
