Top 8 Priority CVEs
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.
Type confusion in V8 (Chrome's JavaScript engine) in versions prior to 152.0.7977.82 enables unauthenticated remote attackers to execute arbitrary code within Chrome's renderer sandbox by enticing a user to visit a specially crafted HTML page. The flaw exploits V8's type system, allowing an attacker to manipulate object type metadata in the JavaScript heap to gain controlled memory access and code execution inside the renderer process. No public exploit or CISA KEV listing has been identified at time of analysis, though V8 type confusion vulnerabilities in Chrome have historically attracted rapid weaponization given the browser's enormous attack surface and attacker interest.
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.
Unrestricted file upload in the Embed HTML5 Game WordPress plugin (versions through 1.3) lets unauthenticated attackers upload arbitrary files - including PHP scripts - because the plugin neither restricts who may upload nor validates file type, enabling planting of PHP backdoors and full remote code execution. WPScan reports the flaw with a publicly available exploit, and the CVSS 10.0 rating reflects unauthenticated network exploitation with complete impact. No CISA KEV listing exists, but the combination of PR:N and a public PoC makes opportunistic scanning likely.
Remote code execution in the WatchMan-Site7 WordPress plugin (all versions through 4.2.0) allows any authenticated user - including a low-privilege subscriber - to run arbitrary PHP on the server because the plugin's debugging console, which evaluates user-supplied PHP, is not access-restricted. Publicly available exploit code exists (reported by WPScan), and with CVSS 9.9 this represents full server compromise from the lowest authenticated role. There is no public evidence of active in-the-wild exploitation at time of analysis.
Unauthenticated arbitrary file upload in the Developer Tools WordPress plugin (versions through 1.1.3) lets remote attackers upload malicious files via the bundled, legacy SWFUpload component, typically leading to remote code execution when a PHP webshell is placed in a web-accessible directory. Any WordPress site running this plugin at or below 1.1.3 is exposed with no authentication required. Publicly available exploit code exists (reported by WPScan), though there is no public evidence of active exploitation.
Site takeover in the SEO Flow by LupsOnline WordPress plugin (versions 3.0.0 through before 3.0.3) stems from improper validation of the credential supplied with the plugin's API requests, allowing unauthenticated attackers to be served in the security context of the administrator who configured the plugin. Because the flaw grants effective administrator-level access, an attacker can fully compromise the affected WordPress site. Publicly available exploit code exists (published by WPScan), though EPSS remains low at 0.15% (4th percentile), and there is no public exploit identified as active in the wild.
Command injection in QVidium Opera11 (firmware 3.3.2a26-Ax4x-opera11) lets remote attackers run arbitrary OS commands by manipulating the ipaddr argument of the /cgi-bin/net_tr.cgi CGI script. The flaw is remotely reachable without authentication and publicly available exploit code exists, but it is not listed in CISA KEV. Because QVidium has ceased operations, no fix will ever be issued, making every deployed unit permanently vulnerable.
