CVE-2026-2540

8.4 highEPSS 0.2%

High (8.4). EPSS 0.2% chance of exploitation in the next 30 days.

The Micca KE700 system contains flawed resynchronization logic and is vulnerable to replay attacks. This attack requires sending two previously captured codes in a specific sequence. As a result, the system can be forced to accept previously used (stale) rolling codes and execute a command. Successful exploitation allows an attacker to clone the alarm key. This grants the attacker unauthorized access to the vehicle to unlock or lock the doors.
