CVE-2025-67135Public exploit

Physical alarm disarming via fixed-code RF replay

Published Feb 11, 2026 · Updated Feb 11, 2026

Authentication replay in the PGST PG107 Alarm System 1.25.05.hf allows physically proximate attackers to disarm it via PF-50 keyfob RF signals. The PF-50 1.2 keyfob transmits a static 433.92 MHz bitstream, and the base station accepts matching UID and command bits without checking freshness or sequence. Capturing one legitimate Disarm transmission within radio range is sufficient to rebroadcast it indefinitely and change the alarm state without triggering an alert.
