Google Chrome flags my Vercel preview deployment as dangerous — Safe Browsing warning - Help

Hello Vercel Community,

I'm investigating a Google Chrome Safe Browsing warning affecting a preview deployment of our educational research platform, NEXO Ciência.

Project: nexo-ciencia-qa-s1

Affected hostname: nexo-ciencia-qa-s1-irr32uirp.vercel.app

What happened:

Google Chrome displayed a red "Dangerous site" warning when accessing this preview URL.

What we have already verified:

The Vercel deployment is READY and has no reported build errors.
The original GitHub CI checks passed.
Google Transparency Report returned "No data available".
Vercel Authentication is enabled.
We removed the affected hostname from our authentication provider's trusted origins.
A separate dependency security audit found advisories that we are investigating. We have not established any connection between those findings and the browser warning.

Questions for the Vercel team:

Could this preview hostname have been flagged by an automated phishing or abuse detection system?
Is there a way to identify whether this is a false positive or a genuine security classification?
What is the recommended procedure to investigate and resolve the warning without disabling browser security?
Can this issue be escalated to the appropriate Vercel security team?

We are keeping the affected preview out of use while the investigation continues.

Thank you for your assistance.
