cisa kev catalog

About this tag
The CISA KEV Catalog is a list of known exploited vulnerabilities that CISA has confirmed are being actively exploited in the wild. This tag covers CISA's additions to the catalog, including flaws in enterprise tools like Citrix NetScaler, Microsoft SharePoint, ConnectWise ScreenConnect, and various other software. Each addition signals that the vulnerability is no longer theoretical but a live threat requiring immediate remediation, especially for federal agencies under Binding Operational Directives. Discussions emphasize the operational importance of the KEV catalog as a prioritization tool for security teams, highlighting the need to patch quickly once a CVE is listed.
