Evidence confidence: Exploitation recorded
● Hype ● Reality
Earlier evidence-support scores are retained in history; this chart shows only the current priority definition.
First record: hype 0.0 · reality 8.2 (2026-11-02 15:11). The curve appears once the score changes.
Public exploit entries / repo candidates
Source entries and unverified repository candidates are counted separately.
Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs.
