CISA Adds Four Known Exploited Vulnerabilities to Catalog

The Cybersecurity and Infrastructure Security Agency (CISA) has added four vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation, the agency announced. The new entries are:

- CVE-2026-75650: Adobe Commerce and Magento Improper Neutralization of Special Elements Used in a Template Engine Vulnerability
- CVE-2026-81963: Microsoft Windows Link Following Vulnerability
- CVE-2026-85880: Microsoft Windows Heap-Based Buffer Overflow Vulnerability
- CVE-2026-86218: N-able N-central Static Code Injection Vulnerability

CISA noted that these types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. The directive reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by CVEs listed in the 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. Organizations aware of an exploited vulnerability not currently listed in the KEV Catalog can submit it for potential addition through CISA's KEV Nomination Form.
