Authenticated command injection in Ubiquiti UniFi OS allows low-privileged network-adjacent attackers to execute arbitrary OS commands on UniFi gateways, controllers, NVRs, and NAS devices, with a CVSS 9.9 score reflecting scope change and full CIA impact. The vulnerability affects a broad device family including UDM, UDM Pro/SE/Max/Beast, UDR, UDW, UCG, UNVR, and UNAS lines per Ubiquiti Security Advisory Bulletin 065. No public exploit identified at time of analysis and the issue is not currently listed in CISA KEV.

Privilege escalation in Ubiquiti UniFi OS allows a low-privileged attacker with network access to elevate privileges on affected UniFi OS devices and instances due to improper input validation (CWE-20). The CVSS 9.9 score reflects a scope-changing impact spanning UniFi Dream Machine, UniFi Express, UDR, UCG, UNVR, UNAS, and other UniFi OS Server platforms. No public exploit identified at time of analysis, and the vulnerability is not currently listed in CISA KEV.

Information disclosure in Ubiquiti UniFi OS devices allows unauthenticated network-adjacent attackers to read sensitive data via a path traversal flaw (CWE-22). The high CVSS 8.6 score reflects a scope change with high confidentiality impact, indicating that disclosed data can affect resources beyond the vulnerable component itself. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Reflected cross-site scripting (XSS) in Smoothwall Express versions before 3.1 Update 13 allows unauthenticated remote attackers to execute arbitrary JavaScript in users' browsers by crafting malicious URLs with javascript: schemes and delivering them through the unsanitized /redirect.cgi endpoint. The vulnerability requires user interaction (clicking a malicious link) and results in limited scope impact affecting user confidentiality and integrity. No public exploit code or active exploitation has been identified at time of analysis.

Stored cross-site scripting in Smoothwall Express prior to version 3.1 Update 13 allows authenticated attackers to inject arbitrary JavaScript through the VPN_IP parameter in /cgi-bin/vpnmain.cgi, which executes when other users view affected VPN configuration pages. The vulnerability requires user interaction (page view) and authenticated access, limiting immediate risk but enabling persistent session hijacking or credential theft against administrative users. No public exploit code or active exploitation has been confirmed at the time of analysis.

Servify Express, a Node.js package for starting Express servers, contains a denial of service vulnerability caused by the absence of size limits on JSON request bodies parsed by express.json(). Attackers can exploit this by sending extremely large payloads to cause memory exhaustion and crash the application process. With an EPSS score of 0.07% (21st percentile), active exploitation remains low-probability, though a patch is available and the vulnerability affects any internet-facing application using affected versions.

Denial of Service vulnerability in Multer (Node.js multipart form-data middleware) affecting versions 1.4.4-lts.1 through 2.0.0 where an attacker can crash the application process by uploading a file with an empty string field name, triggering an unhandled exception. The vulnerability has a CVSS score of 8.7 indicating high severity, though the impact is limited to availability (DoS) rather than confidentiality or integrity. No active exploitation or public POC has been confirmed at this time, but the low attack complexity and network accessibility make this a practical DoS vector for any exposed Multer instance.

A vulnerability has been identified in the Express response.links function, allowing for arbitrary resource injection in the Link header when unsanitized data is used. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Express.js minimalist web framework for node. Rated medium severity (CVSS 4.7), this vulnerability is remotely exploitable, no authentication required. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.

Express.js minimalist web framework for node. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Open Redirect vulnerability could allow attackers to redirect users to malicious websites via URL manipulation.

qs before 6.10.3, as used in Express before 4.17.3 and other products, allows attackers to cause a Node process hang for an Express application because an __ proto__ key can be used. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

The Express web framework before 3.11 and 4.x before 4.5 for Node.js does not provide a charset field in HTTP Content-Type headers in 400 level responses, which might allow remote attackers to. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.

The EXPRESS (aka com.gpshopper.express.android) application 2.5.3 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain. Rated medium severity (CVSS 5.4). No vendor patch available.
