CISA has added seven new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: to view the newly added vulnerabilities in the catalog, click on the arrow in the “Date Added to Catalog” column, which will sort by descending dates. 
 
Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known CVEs that carry significant risk to the federal enterprise. BOD 22-01 requires 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 Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the Catalog that meet the specified criteria.

CISA—through the Joint Cyber Defense Collaborative (JCDC)—has released a toolkit of free cybersecurity resources for the election community. The toolkit aims to help state and local government officials, election officials, and vendors enhance the cybersecurity and cyber resilience of U.S. election infrastructure. The toolkit resources, which come from CISA, JCDC members, and others across the cybersecurity community, focus on assessing risk and protecting election infrastructure assets commonly targeted by phishing, ransomware, and distributed denial-of-service (DDoS) attacks.

CISA strongly encourages election community stakeholders to use the Cybersecurity Toolkit to Protect Elections to strengthen the cybersecurity and cyber resilience of U.S. election infrastructure.
