The NR7103 has been affected by a series of vulnerabilities across different firmware versions. The most critical issues are summarized below:

In the sprawling server farm of a mid-sized logistics company, a single Zyxel NR7103 router had been quietly doing its job for two years. It sat atop a metal rack near a dusty window, blinking its green LEDs in a steady, unbothered rhythm. It wasn’t the newest or fastest device on the network, but it was reliable—the digital equivalent of an old pickup truck that always started on a cold morning.

Post-Authentication Command Injection (CVE-2025-13943 & CVE-2026-1459)

The progress bar crawled across his screen.

This is the most severe vulnerability affecting the NR7103, discovered in February 2026. It is a command injection flaw in the device's UPnP (Universal Plug and Play) function. A remote attacker could send specially crafted UPnP SOAP requests to execute arbitrary operating system commands on the device—. With a CVSS score of 9.8 (Critical) , an attacker gaining such access could completely compromise the device, steal data, install malware, or use it as a foothold for lateral movement within a network. Zyxel noted that WAN access to UPnP is disabled by default, significantly reducing the risk unless users have manually enabled it.
