CISA Adds One Known Exploited Vulnerability to Catalog

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

• CVE-2026-20182 Cisco Catalyst SD-WAN Controller Authentication Bypass Vulnerability

This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise.

Note: Please adhere to CISA’s guidelines to assess exposure and mitigate risks associated with Cisco SD-WAN devices as outlined in Emergency Directive 26-03: Mitigate Vulnerabilities in Cisco SD-WAN Systems and Supplemental Direction ED 26-03: Hunt and Hardening Guidance for Cisco SD-WAN Systems. Adhere to the applicable Binding Operational Directive (BOD) 22-01 guidance for cloud services or discontinue use of the product if mitigations are not available.

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.
