Where to get the vulnerability fix firmware for mobile routers?

Zyxel_HsinBo

If you are looking to secure your mobile router against recent vulnerabilities (such as CVE-2026-1460), here is how you can access the appropriate firmware fixes and what you need to know before upgrading.

Step 1: Check the Official Announcement First

Before downloading any files, please visit our dedicated community category to read the corresponding announcement post for your specific model:

👉 Nebula Mobile Router Vulnerability Announcements

⚠️ Important Notice: Please be fully aware that upgrading to a "V0" security patch image will cause the device to temporarily lose its Nebula cloud management functionality.

Because mobile routers typically operate over cellular networks behind an ISP’s Carrier-Grade NAT (CGNAT), the practical exploitation risk is generally low. If you do not have an urgent requirement, we recommend waiting for the next official Nebula firmware release, which will include the fix without losing cloud management.

Step 2: How to Request the V0 Firmware

If you have evaluated the impact, accept the temporary loss of Nebula management, and still want to proceed with the V0 firmware upgrade immediately, please use one of the following methods to request the file:

1. Contact Local Support: Reach out directly to your local Zyxel support team or open an eITS/Zendesk ticket.
2. Create a Community Post: Create a new inquiry post here in the community, and an authorized Zyxel representative will assist you individually.

Note: To ensure proper risk awareness, V0 security patches are distributed strictly on a request-only basis and are not provided via public direct download links.
