CVE-2026-18411 is a vulnerability in dealer-installed KARR Security System and SWDS automotive anti-theft systems, including Acrisure KARR BT and DR-100 versions prior to July 20, 2026. The affected devices use a shared Bluetooth authentication key across impacted units rather than a unique per-device key. Because Bluetooth authentication relies on a common key, an attacker in Bluetooth proximity can authenticate to the system and issue unauthorized commands to the connected vehicle. Reported impacts include unauthorized activation of vehicle functions such as door unlocking and engine immobilization. The issue is classified as CWE-321.
