CISA Adds Four Known Exploited Vulnerabilities to Catalog

CISA has added four actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: Microsoft Configuration Manager SQL Injection (CVE-2024-43468), Notepad++ Download Code Without Integrity Check (CVE-2025-15556), SolarWinds Web Help Desk Security Control Bypass (CVE-2025-40536), and Apple Multiple Buffer Overflow (CVE-2026-20700). These vulnerabilities represent significant risk to federal enterprise networks and are frequent attack vectors for malicious cyber actors. Under BOD 22-01, FCEB agencies must remediate these vulnerabilities by specified due dates. CISA strongly urges all organizations to prioritize timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice to reduce exposure to cyberattacks.

CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2024-43468 Microsoft Configuration Manager SQL Injection Vulnerability CVE-2025-15556 Notepad++ Download of Code Without Integrity Check Vulnerability CVE-2025-40536 SolarWinds Web Help Desk Security Control Bypass Vulnerability CVE-2026-20700 Apple Multiple Buffer Overflow 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 .
