CISA Adds Two Known Exploited Vulnerabilities to Catalog

CISA has added two actively exploited RoundCube Webmail vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2025-49113 (deserialization of untrusted data leading to potential RCE) and CVE-2025-68461 (cross-site scripting). These vulnerabilities pose significant risks as frequent attack vectors for malicious cyber actors targeting federal and civilian networks. Under BOD 22-01, FCEB agencies must remediate these vulnerabilities by specified deadlines. CISA strongly advises all organizations using RoundCube to prioritize immediate patching and vulnerability remediation as part of their security posture. Failure to address these vulnerabilities could result in unauthorized system access, data compromise, or network infiltration through webmail attack vectors.

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2025-49113 RoundCube Webmail Deserialization of Untrusted Data Vulnerability CVE-2025-68461 RoundCube Webmail Cross-site Scripting 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 .
