> CISA added three known-exploited vulnerabilities to its KEV Catalog, including embedded malicious code flaws in Daemon Tools Lite and Nx Console.

CISA has added three vulnerabilities to its Known Exploited Vulnerabilities Catalog based on evidence of active exploitation in the wild. The additions are CVE-2026-8398 (Daemon Tools Lite embedded malicious code), CVE-2026-45321 (TanStack unspecified vulnerability), and CVE-2026-48027 (Nx Console embedded malicious code). These vulnerabilities represent frequent attack vectors leveraged by malicious cyber actors and pose significant risks to the federal enterprise.

Under Binding Operational Directive 22-01, Federal Civilian Executive Branch agencies are required to remediate these vulnerabilities by specified due dates. While BOD 22-01 applies only to FCEB agencies, CISA urges all organizations to prioritize remediation of KEV Catalog vulnerabilities as part of their vulnerability management programs. The presence of embedded malicious code in two of the three vulnerabilities suggests supply-chain or installation-time compromise risks that warrant immediate attention.

## Mentioned in this report

- Vulnerabilities: CVE-2026-45321 (KEV), CVE-2026-48027 (KEV), CVE-2026-8398 (KEV)
