CVE-2026-18411
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
KARR Security System and SWDS dealer-installed automotive anti-theft systems use a shared Bluetooth authentication key across affected devices. An attacker within Bluetooth range can issue unauthorized commands to the vehicle, potentially allowing unauthorized access to vehicle functions, including door unlocking and engine immobilization.
Risk Assessment
An attacker near the vehicle can take control of security functions, potentially leading to vehicle theft or unauthorized access. The shared key increases the scope of the threat.
Recommendation
Contact the manufacturer for firmware updates or key changes. Limit Bluetooth range and monitor for unauthorized connections.
