CVE-2026-49319

Remote Keyless Entry System (RKES), using the 433 MHz key fob bearing FCC ID CWTR53R0 manufactured by ALPS ALPINE CO., LTD., is vulnerable to a roll-back attack against its rolling-code authentication. An attacker within RF range who records two consecutive lock or unlock transmissions from a legitimate key fob can later replay the same pair of transmissions repeatedly. During testing, replaying the first captured transmission caused the RKES to enter a state in which replaying the second captured transmission resulted in a successful lock or unlock operation of the vehicle. Tested and confirmed on a 2024 Suzuki Swift (SWIFT ISG GLS AC 1.2 5P 4x2 TM).
