CVE-2026-36829

Panabit PAP-XM320 routers running firmware version 7.7 or earlier have a flaw that lets attackers bypass the login screen. By sending a specially crafted cookie, an attacker can trick the device into thinking they are already logged in and gain full control. This flaw is serious because it gives attackers unrestricted access to the router.
