Executive Summary
CISA has added seven new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, indicating active exploitation in the wild. The vulnerabilities affect Microsoft products (Visual Basic for Applications, Exchange Server, Windows), Adobe Acrobat and Reader, and Fortinet products. The types include Insecure Library Loading, Use-After-Free, Deserialization of Untrusted Data, Out-of-Bounds Read, Link Following, and Prototype Pollution vulnerabilities. These represent significant risk to federal networks as they are frequent attack vectors. While Binding Operational Directive 22-01 applies only to Federal Civilian Executive Branch agencies, CISA strongly urges all organizations to prioritize timely remediation of these KEV vulnerabilities as part of their vulnerability management practice to reduce exposure to cyberattacks.
Summary
CISA has added seven new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2012-1854 Microsoft Visual Basic for Applications Insecure Library Loading Vulnerability CVE-2020-9715 Adobe Acrobat Use-After-Free Vulnerability CVE-2023-21529 Microsoft Exchange Server Deserialization of Untrusted Data Vulnerability CVE-2023-36424 Microsoft Windows Out-of-Bounds Read Vulnerability CVE-2025-60710 Microsoft Windows Link Following Vulnerability CVE-2026-21643 Fortinet SQL Injection Vulnerability CVE-2026-34621 Adobe Acrobat and Reader Prototype Pollution Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria .
