Note: To view other 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 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 Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

Today, the Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) released an update to joint Cybersecurity Advisory (CSA) #StopRansomware: Royal Ransomware. The updated advisory provides network defenders with additional information on tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) associated with Royal ransomware variants. FBI investigations identified these TTPs and IOCs as recently as June 2023. Royal ransomware attacks have spread across numerous critical infrastructure sectors including, but not limited to, manufacturing, communications, healthcare and public healthcare (HPH), and education. CISA encourages network defenders to review the updated CSA and to apply the included mitigations. See #StopRansomware for additional guidance on ransomware protection, detection, and response.
