CVE-2026-47368 HIGH PATCH This Week

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.

CVE-2026-27508 MEDIUM PATCH This Month

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.

CVE-2026-26352 MEDIUM PATCH This Month

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.

CVE-2025-67731 npm HIGH PATCH This Week

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.

CVE-2025-48997 npm HIGH PATCH This Week

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.
