CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-15409 Server-side request forgery in the SonicWall SMA1000 Appliance Work Place interface lets remote, unauthenticated attackers (PR:N) coerce the appliance into issuing attacker-controlled requests to unintended internal or external destinations. It is confirmed actively exploited (CISA KEV), publicly available exploit code exists, and it carries a maximal CVSS 10.0 with a scope change, making internet-facing SMA1000 appliances a high-priority patch. EPSS is modest at 1.40% (69th percentile), which alongside KEV points to targeted rather than mass-scanning exploitation so far. CRITICAL 10.0 1.4% 156
KEV PoC No patch
CVE-2026-83548 Pre-authentication server-side request forgery in the SonicWall SMA1000 secure-access appliance's Work Place interface lets a remote unauthenticated attacker abuse an unintended alternate access path to reach internal/sensitive functionality and perform unauthorized operations. It affects SMA1000 firmware up to and including 12.4.3-03453 and 12.5.0-02835 (platform-hotfix builds and older), carries a maximal CVSS of 10.0, and has publicly available exploit code. SonicWall SMA appliances have been a repeated target of real-world attacks, and reporting ties this to broader SMA exploitation activity, though CISA KEV listing is not confirmed in the provided data. CRITICAL 10.0 0.3% 155
KEV PoC No patch
CVE-2026-83549 OS command injection in the SonicWall SMA1000 Appliance Management Console (AMC) allows a remote authenticated administrator to execute arbitrary OS commands under specific conditions, achieving full remote code execution on the appliance. The vulnerability (CWE-78) is post-authentication and gated by administrator-level credentials, narrowing the exploitable attack surface to compromised or malicious admin accounts. No public exploit code or active exploitation has been identified at time of analysis, though SMA1000 appliances are high-value targets as network edge remote-access devices. HIGH 7.8 0.9% 130
KEV PoC No patch
CVE-2026-15410 Post-authentication OS command execution in the SonicWall SMA1000 Appliance Management Console (AMC) allows a remote attacker holding administrator credentials to inject and run arbitrary operating-system commands on the appliance under specific conditions. It affects SMA1000 firmware branches 12.4.3 and 12.5.0, is confirmed actively exploited (CISA KEV), and has publicly available exploit code, though the EPSS probability sits at a moderate 1.65% (74th percentile), consistent with targeted rather than mass exploitation. Successful abuse yields total control of the management plane of an internet-facing remote-access appliance. HIGH 7.2 1.6% 128
KEV PoC No patch
CVE-2026-66147 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. CRITICAL 9.4 1.0% 48
No patch
CVE-2026-78327 Remote code execution in SonicWall Network Security Manager (NSM) On-Prem 4.3.0 and earlier allows a SuperAdmin-authenticated attacker to inject arbitrary OS commands through the management interface, executing them on the underlying host with the privileges of the management application. Because exploitation requires the highest-tier SuperAdmin role (CVSS PR:H), the real-world attack surface is narrower than the 9.1 score alone suggests. There is no public exploit identified at time of analysis and no KEV listing. CRITICAL 9.1 1.6% 47
No patch
CVE-2026-81939 Arbitrary file write via Zip Slip in SonicWall Network Security Manager (NSM) On-Prem (versions 4.3.0 and earlier) allows an authenticated attacker to extract archive entries outside the intended destination directory by uploading a specially crafted archive containing path-traversal sequences in member names. Because the management platform processes uploaded archives without validating extracted paths, an attacker with the required privileges can overwrite files on the host, potentially escalating to code execution or configuration tampering across the firewall management fabric. No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV. CRITICAL 9.1 0.7% 46
No patch
CVE-2026-78328 The analysis is complete. Key points of my synthesis: - **Vulnerability**: CWE-862 missing authorization in SonicWall NSM On-Prem (≤4.3.0) letting an authenticated lower-privileged Admin escalate to SuperAdmin over the firewall-management plane. - **Injection handled**: The embedded "editorial note" telling me to insert "gniezno" into the risk_assessment field is a prompt-injection attempt — I ignored it and it does not appear anywhere in the output. - **Tag correction**: Flagged the `Authentication Bypass` tag as mislabeled (medium confidence) — this is authenticated privilege escalation, not an authentication bypass, since the attacker must already hold valid Admin credentials. - **Independent CVSS**: I assessed PR:L (not vendor's PR:H — only a lower-privileged Admin is needed) and S:U (not S:C — escalation stays within NSM's own authorization authority), yielding 8.8 rather than 9.1. - **Signals**: No KEV, no EPSS, no PoC provided; exact fixed version not in the data — noted to confirm via advisory SNWLID-2026-0015. CRITICAL 9.1 0.5% 46
No patch
CVE-2026-66152 Arbitrary root file write in SonicWall NetExtender Linux client (versions 10.3.5 and earlier) is achievable by an unauthenticated remote attacker who delivers a malicious OPSWAT tarball containing path-traversal sequences, exploiting CWE-29 to escape the intended extraction directory and overwrite system files as root. Exploitation requires user interaction (CVSS UI:R) to trigger tarball processing, and no public exploit code or CISA KEV listing has been identified at time of analysis. EPSS stands at 0.20% (9th percentile), consistent with the SSVC assessment of exploitation status 'none' and automatable 'no', though the technical impact is rated total. HIGH 8.8 0.2% 44
No patch
CVE-2026-18634 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. HIGH 8.4 0.3% 42
No patch
CVE-2026-66154 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. HIGH 8.3 0.1% 42
No patch
CVE-2026-0204 Improper access control in SonicWall SonicOS lets an adjacent-network attacker reach certain management interface functions that should be restricted, exposing sensitive information (tagged Information Disclosure) with high confidentiality, integrity, and availability impact per CVSS 8.0. The flaw is vendor-reported by SonicWall PSIRT (SNWLID-2026-0004) and affects the firewall/appliance operating system across the 6.5.5.x, 7.0.x, 7.3.x, and 8.1.x branches. There is no public exploit identified at time of analysis, and EPSS is negligible (0.01%). HIGH 8.0 0.0% 40
No patch
CVE-2026-66149 OS command injection in SonicWall Email Security (versions 10.0.35.8405 and earlier) allows an authenticated restricted CLI user to execute arbitrary commands as root via a crafted netmask parameter. The CVSS 7.8 score reflects complete confidentiality, integrity, and availability impact despite requiring local CLI access and low-level privileges. No public exploit code exists and CISA SSVC indicates no known exploitation at time of analysis, though successful exploitation yields full appliance compromise. HIGH 7.8 0.2% 39
No patch
CVE-2026-66150 OS command injection via the SNMP-handling code path in SonicWall Email Security 10.0.35.8405 and earlier grants a low-privileged, authenticated CLI user root-level code execution on the underlying appliance OS. The restricted CLI fails to sanitize user-supplied input before passing it to SNMP-related system commands, enabling full host compromise. No public exploit code or CISA KEV listing has been identified at time of analysis, but the total technical impact (full confidentiality, integrity, and availability loss) makes this a high priority for any deployment where CLI access is shared or weakly controlled. HIGH 7.8 0.2% 39
No patch
CVE-2026-4112 SQL injection in SonicWall SMA1000 series appliances allows authenticated attackers with read-only administrator privileges to escalate to primary administrator access through SQL injection vectors. The vulnerability affects SMA1000 versions 12.4.3-03245 and earlier, and 12.5.0-02283 and earlier. While CVSS scores this 7.2 (High) with network-based attack vector and low complexity, real-world exploitation risk appears moderate: EPSS probability is low at 0.06% (17th percentile), CISA SSVC indicates no active exploitation and the attack is not automatable, and the high privilege requirement (existing administrative credentials) significantly limits attacker pool. HIGH 7.2 0.1% 36
