{"id":"CVE-2026-49319","state":"PUBLISHED","title":"Alps Electric Co., Ltd. R53R0 Remote Keyless Entry System (RKES) Replay Attack","description":"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. \n\n\n\nAn 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).","publishedAt":"2026-06-25T14:11:18.921Z","updatedAt":"2026-06-26T05:00:00.212Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:N/SI:L/SA:N","source":"ASRG"},"assigner":"ASRG","products":["Alps Electric Co., Ltd.
