Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.","CISA has updated its Known Exploited Vulnerabilities (KEV) Catalog with six new entries, citing evidence of active exploitation. These vulnerabilities, including issues in Red Hat products, Microsoft SQL Server, Ajax.NET, Linux Kernel, and Citrix NetScaler, are considered significant risks. The update reinforces CISA's Binding Operational Directive 26-04, which mandates federal agencies to prioritize patching these high-risk vulnerabilities on public-facing assets.","CISA adds six actively exploited vulnerabilities to its KEV Catalog.","Alert CISA Adds Six Known Exploited Vulnerabilities to Catalog Release DateAugust 26, 2026 CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
