Summaries are excerpts from the publishers. The default Advisories view includes CISA KEV, CISA Industrial and CERT-EU. When several scores exist, PATCHBAY shows the newest valid CVSS version, then prefers a primary assessment, NVD, and a stable assessor ordering. Open the original for all assessments. CISA Known Exploited dates indicate catalog additions. This product uses data from the NVD API but is not endorsed or certified by the NVD.
