@cR0w @nixCraft RSS would be nice but it does have an open, machine-readable API:

https://euvdservices.enisa.europa.eu/api/lastvulnerabilities

Edit: this one seems even better: hxxps://euvdservices.enisa.europa.eu/api/vulnerabilities?assigner=&product=&vendor=&text=&fromDate=&toDate=&fromScore=0&toScore=10&fromEpss=0&toEpss=100&exploited=true&page=0&size=10
