SonicWall has warned of two vulnerabilities impacting end-of-life Global Management System (GMS) systems that it said will not be patched.
Details of the security flaws, which affect SonicWall GMS 9.5.2 and earlier versions, are below –
- CVE-2026-109593 (CVSS score: 9.1) – An unauthenticated file read vulnerability that could allow an attacker with network access to read internal GMS files, potentially exposing sensitive information.
- CVE-2026-109594 (CVSS score: 6.8) – A post-authentication SQL injection vulnerability that could allow an authenticated attacker to access or modify information stored in the GMS database under specific conditions.
“The affected product has reached End-of-life (EoL),” SonicWall said in a Tuesday alert.
“As a result, no remediation or security update will be released for these vulnerabilities. Organizations using the product should be aware of the associated security risks and are strongly encouraged to upgrade to the SonicWall Network Security Manager (NSM).”
The development comes less than a month after SonicWall shipped fixes for CVE-2026-102255 (CVSS score: 10.0), a critical pre-authenticated server-side request forgery (SSRF) flaw that could have allowed an attacker to reach internal functionality and perform unauthorized operations.
The vulnerability has since come under active exploitation in the wild, with telemetry data from Previdian recording 2,541 attack attempts from eight unique IP addresses from Singapore and the U.S. since October 9, 2026. As many as 30 exploitation attempts were registered on November 3, 2026.
