CVE-2026-18634 HIGH This Week

Insecure deserialization in SonicWall Global Management System (GMS) 9.5.1 (Build 9510.1044) and earlier enables a local attacker who can interact with the affected service to perform unauthorized actions resulting in full compromise of confidentiality, integrity, and availability. The root cause is CWE-502: the service deserializes attacker-controlled objects without adequate validation, allowing manipulation of application logic or execution of unintended code paths. No public exploit or CISA KEV listing has been identified at time of analysis; EPSS places exploitation probability in the 18th percentile, indicating low current exploitation interest despite a high CVSS score.

CVE-2026-66154 HIGH This Week

Insufficient certificate validation in SonicWall Global Management System (GMS) 9.5.1 (Build 9510.1044) and earlier exposes a privileged internal communication workflow to man-in-the-middle interception, enabling an attacker with adjacent network access to present a fraudulent certificate the application accepts without proper verification. Under controlled network conditions allowing a successful MitM position, an unauthenticated attacker (per CVSS PR:N) can read, modify, or inject data into what GMS treats as a trusted management channel, resulting in unauthorized configuration changes that propagate to managed SonicWall infrastructure. No active exploitation has been confirmed (SSVC exploitation: none) and no public exploit is identified at time of analysis, though the S:C scope change elevates potential downstream impact across the full managed appliance fleet.

CVE-2026-66148 MEDIUM This Month

Command injection in SonicWall Global Management System (GMS) CLI version 9.5.1 and earlier enables a low-privileged user to execute arbitrary system commands with root privileges, constituting a full local privilege escalation on the GMS management host. The flaw is rooted in CWE-94 (Code Injection) within the CLI component, where unsanitized user input reaches a system command interpreter running at elevated privilege. No active exploitation has been confirmed by CISA KEV, no public exploit code has been identified, and SSVC assessment characterizes exploitation status as none with a non-automatable attack path.

CVE-2026-66147 CRITICAL Act Now

Remote code execution in SonicWall Global Management System (GMS) 9.5.1 and earlier is possible through an unauthenticated command injection flaw in the GMS Dispatcher Service, letting remote attackers run arbitrary operating-system commands on the management server via specially crafted requests. Because GMS centrally administers fleets of SonicWall firewalls, a compromise cascades into control over every managed appliance. No public exploit identified at time of analysis, though the CVSS 9.4 rating and 'total' technical impact make this a high-priority patch target.
