CISA Adds One Known Exploited Vulnerability to Catalog

CISA has added CVE-2026-25108 to its Known Exploited Vulnerabilities (KEV) Catalog, a command injection vulnerability affecting Soliton Systems K.K. FileZen. This vulnerability is being actively exploited and poses significant risks to federal enterprise networks. The addition stems from Binding Operational Directive (BOD) 22-01, which mandates that Federal Civilian Executive Branch agencies remediate identified vulnerabilities by specified deadlines. While BOD 22-01 applies only to federal agencies, CISA strongly advises all organizations to prioritize timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practices. Organizations using Soliton FileZen should immediately patch or implement compensating controls to mitigate exposure to potential compromise.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-25108 Soliton Systems K.K. FileZen OS Command Injection Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses 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 .
