Updated October 22, 2025 

CISA is continually collaborating with partners across government and the private sector. Through this collaboration, CISA has determined that CVE-2025-6264 has not been exploited and there is insufficient evidence to keep this Common Vulnerabilities and Exposures (CVE) on the Known Exploited Vulnerabilities (KEV) and that the best course of action is to remove it. CISA is committed to continued collaboration with partners. 

End of Update 

CISA has added five new vulnerabilities to its KEV Catalog, based on evidence of active exploitation.

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 KEV established the KEV Catalog as a living list of known CVE (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.
