CVE-2026-2541

This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code.

MEDIUM 6.4EPSS 0.19%

Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

Description

The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle.
