The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added two high-severity security flaws impacting Broadcom Brocade Fabric OS and Commvault Web Server to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation in the wild. The vulnerabilities in question are listed below - CVE-2025-1976 (CVSS score: 8.6) - A code injection flaw

CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2025-1976 Broadcom Brocade Fabric OS Code Injection Vulnerability CVE-2025-42599 Qualitia Active! Mail Stack-Based Buffer Overflow Vulnerability CVE-2025-3928 Commvault Web Server Unspecified 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 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.
