CVE-2026-41038

Description

This vulnerability exists in Quantum Networks router due to lack of enforcement of strong password policies in the web-based management interface. An attacker on the same network could exploit this vulnerability by performing password guessing or brute-force attacks against user accounts, leading to unauthorized access to the targeted device.
