Year columns: bugs added to CISA’s exploited list (darker is more). *2026 is the year so far. Zero-day, time to exploit, ransomware and VEDAS rules cover 2025 and 2026: zero-day means CISA listed the bug on or before the day its CVE was published; time to exploit is days from CVE publication to CISA listing; VEDAS rules counts remotely exploitable bugs that have a free detection rule.
