In the news
No security story in the last 14 days named Synacor in its headline.
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.
