CVE-2025-34253Network attack vector

Stored XSS via unsanitized Network field

Published Oct 16, 2025 · Updated Oct 16, 2025

Stored XSS in D-Link Nuclias Connect 1.3.1.4 and earlier allows remote authenticated users to run JavaScript in other users' browsers. The profile configuration workflow stores the Network field without proper sanitization when a profile is created or edited and later renders the value to viewers. Profile-editing access is required, and exploitation exposes data and actions available to a user who views the malicious profile entry.
