CVE-2026-18411

Unauthorized vehicle control via shared Bluetooth key

Published Aug 5, 2026 · Updated Aug 5, 2026

Hard-coded key use in Acrisure Protection Group KARR BT and DR-100 before July 20, 2026 allows physically proximate attackers to control vehicles. Each affected device accepts Bluetooth authentication with the same embedded key, so possession of that common secret authorizes commands across installations. Bluetooth range is required; successful commands can unlock doors or activate engine immobilization without prior device-specific authorization.
