What changed
CISA has added two Microsoft vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation. The additions include CVE-2009-0238 affecting Microsoft Office and CVE-2026-32201 affecting Microsoft SharePoint Server. Both vulnerabilities have been identified as frequent attack vectors for malicious cyber actors.
Federal Civilian Executive Branch agencies must remediate these vulnerabilities by the due dates specified in Binding Operational Directive 22-01. While BOD 22-01 technically applies only to FCEB agencies, CISA strongly urges all organizations to prioritize timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. Organizations should review their systems for these specific CVEs and implement patches or mitigations accordingly.
What to do next
- Review the KEV Catalog for CVE-2009-0238 and CVE-2026-32201
- Prioritize remediation of these vulnerabilities as part of vulnerability management
- FCEB agencies must remediate by the due dates established in BOD 22-01

- CVE-2026-32201 Microsoft SharePoint Server Improper Input Validation 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.
