CISA Adds Six Known Exploited Vulnerabilities to Catalog

CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities Catalog based on confirmed active exploitation in the wild. The list includes flaws affecting Cisco BroadWorks, multiple Barracuda Networks products, Openwave Messaging Webtop Media Transcoder, Microsoft Office Outlook, and Google Chromium. These vulnerabilities enable attacks such as XML external entity injection, OS command injection, authentication bypass, and use-after-free exploitation. Binding Operational Directive 26-04 requires Federal Civilian Executive Branch agencies to prioritize remediation of KEV-listed issues on publicly exposed assets that could grant full system control. CISA encourages all organizations to adopt similar risk-based vulnerability management practices. The agency continues to accept nominations for additional exploited vulnerabilities through its official form.

CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

The newly added entries are:

  • CVE-2026-20320 — Cisco BroadWorks Improper Restriction of XML External Entity Reference Vulnerability
  • CVE-2026-111560 — Barracuda Networks Multiple Products OS Command Injection Vulnerability
  • CVE-2026-111793 — Openwave Messaging Limited Webtop Media Transcoder Incorrect Resource Transfer Between Spheres Vulnerability
  • CVE-2026-116606 — Barracuda Networks Email Security Gateway (ESG) Authentication Bypass Using an Alternate Path or Channel Vulnerability
  • CVE-2026-124194 — Microsoft Office Outlook Missing User Interaction for Potentially Unsafe Action Vulnerability
  • CVE-2026-125350 — Google Chromium Use-After-Free Vulnerability

These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities.

BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities.

CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
