CVE-2025-56448Public exploit

Physical alarm bypass via replayed remote transmissions

Published Sep 15, 2025 · Updated Sep 15, 2025

Capture-replay in Positron PX360BT SW REV 8 allows physically proximate attackers to bypass the car alarm using recorded transmissions. The alarm system fails to rotate rolling codes or invalidate a code after acceptance, leaving the same captured remote-control transmission valid. Exploitation requires recording a valid transmission and replaying it near the vehicle, enabling unauthorized alarm operation and exposing the vehicle to theft.
