Dear Max,
I am a simple user.
Thank you for notifying the community of the unresolved Chromium vulnerabilities.
You can use official channels to report vulnerabilities. Also, if you find these vulnerabilities "dangerous" and underrated, report them to the community as you did with Chronium. You must not leave the community or unsubscribe from this mailing list.
CVE is a database managed in partnership with Homeland Security (USA) and you use an email with warrant canary. You are also an expert in social engineering, you know "Security through obscurity (STO)" (speakeasy-like). And these vulnerabilities are a good "metus hostilis" for a target.
Thank you.
