CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-8398 Daemon Tools Lite Embedded Malicious Code Vulnerability CVE-2026-45321 TanStack Unspecified Vulnerability CVE-2026-48027 Nx Console Embedded Malicious Code 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 .
CISA has added three vulnerabilities to its Known Exploited Vulnerabilities Catalog due to active exploitation: CVE-2026-8398 in Daemon Tools Lite, CVE-2026-45321 in TanStack, and CVE-2026-48027 in Nx Console, all involving embedded malicious code. Two have published CVSS 3.1 scores of 9.8 and 9.6 respectively, and CVE-2026-45321 specifically affects TanStack arktype-adapter versions 1.166.12 and 1.166.15, eslint-plugin-router versions 1.161.9 and 1.161.12, and eslint-plugin-start version 0.0.4. While remediation is mandated for federal agencies, CISA urges all organizations to prioritize patching these catalog entries.
