SonicWall disclosed two SMA 1000 flaws on September 1, both exploited in the wild: CVE-2026-83548, a pre-auth SSRF scoring CVSS 10.0, and CVE-2026-83549, an OS command injection. Chained, they reach unauthenticated RCE. The overlooked part is SonicWall's own guidance for a confirmed compromise — re-image, change all passwords, and reset TOTP tokens. A VPN gateway is an authentication store. A patch closes the code path; it cannot un-copy the seeds an intruder already took.
