How do I check whether I am affected by CVE-2026-10131?

Log in to the router admin page and read the firmware version (System/Status). Exposed if it is TOTOLINK-X2000R-Gh-V1.0.0-B20250421.1327. Also check whether the admin interface (/boafrm/*) answers from the WAN side; remote management should be off.

What is the fix for CVE-2026-10131?

No fixed firmware published as of 2026-10-23 (Talos timeline shows no vendor patch). Mitigate: disable WAN/remote management, use a strong unique admin password, keep mesh mode off if unused, restrict LAN admin access; watch totolink.net for new X2000R firmware.

Who is not affected by CVE-2026-10131?

Not affected if: auth-required, management-interface-not-exposed, other-firmware-version, wan-admin-disabled.
