SonicWall says attackers can bypass SAML authentication—and any SAML-enforced MFA—on SSL-VPN by logging in with valid credentials for another authentication method; researcher Ryan Harris reported the flaw.

The issue affects only SonicOS SSL-VPN services configured to use SAML authentication and carries CVSS severity 7.1. CISA has added CVE-2026-19868 to its Known Exploited Vulnerabilities catalog and ordered federal civilian agencies to secure affected systems by November 20, 2026; SonicWall investigated an exploitation report but shared no details.

Affected versions are SonicOS 7.3.3-7015 and older, and SonicOS 8.2.2-8015 and older. Fixed versions are 7.3.4-7013 and 8.2.3-8015, and SonicWall says no workarounds are available, so customers should install the latest security updates.
