In the news
From CISA's Known Exploited Vulnerabilities catalogue. "Disclosure to CISA's list" uses NVD's publication date and leaves out the 2021-11-03 launch, when CISA added hundreds of older flaws at once; CISA often lists a flaw after attacks have begun, so it's an upper limit on how fast exploitation came.
