CISA Adds SonicWall SonicOS CVE-2026-19868 to Known Exploited Vulnerabilities Catalog

CISA has added one new entry to its Known Exploited Vulnerabilities Catalog after confirming active exploitation in the wild. The vulnerability, tracked as CVE-2026-19868, affects SonicWall SonicOS SSLVPN and stems from the use of single-factor authentication. This flaw allows attackers to bypass stronger authentication controls and gain unauthorized access to VPN services. The addition triggers mandatory remediation timelines for Federal Civilian Executive Branch agencies under Binding Operational Directive 26-04. CISA emphasizes that the vulnerability poses significant risks because successful exploitation can grant attackers full control over affected assets. Organizations outside the federal sector are strongly encouraged to adopt the same risk-based prioritization approach.

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

The entry, identified as CVE-2026-19868, impacts SonicWall SonicOS SSLVPN and involves the use of single-factor authentication. 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) 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.
