@nadia I tried filtering by CVSS score, leaving in only "Critical". There was a single-digit number of those per year. I would read the descriptions and linked writeups for each of them, and after that it usually turned out half of them are clearly not applicable or just pure bullshit.
For the rest I wasn't sure whether we're affected because I didn't know how the application uses them, so I opened tickets for the devs. It turned out half were not applicable either.
And it was a PITA.
