What is github.com/letsencrypt/boulder's Vulert package health score?

Vulert scores github.com/letsencrypt/boulder 96/100, which reads as healthy. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15).

How often are new github.com/letsencrypt/boulder vulnerabilities disclosed?

Which versions of github.com/letsencrypt/boulder are affected?
