Managing security updates for flathub published flatpaks?

I’m trying to determine what updates I should be aware of in any of my installed flatpaks due to CVE vulnerabilities.

Flatpak itself has Security Overview · flatpak/flatpak · GitHub

But I can’t see any similar feed for the flatpaks themselves.

The closest I get is by suscribing to Flathub – recently updated applications in Thunderbird and creating a search folder for the flatpaks I care about.

I’m curious of others here manage this. Nixpks has vulnxscan, npm has the audit subcommand. Ubuntu has a security repo, and a security announce mailing list. What is the Flatpak way?
