common questions

Is CVE-2026-109593 being exploited?

Not confirmed. CVE-2026-109593 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked.

How severe is CVE-2026-109593?

CVE-2026-109593 is rated Critical with a CVSS score of 9.1. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2026-109593?

Not known from our data. No patch reference has been recorded for CVE-2026-109593, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.

What does CVE-2026-109593 affect?

CVE-2026-109593 affects SonicWall Global Management System (GMS) <= 9.5.2. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

What should I do about CVE-2026-109593?

Isolate GMS, restrict network access, apply vendor patch/mitigations immediately
