CVE-2026-2539 Details

A vulnerability exists in the Micca KE700 car alarm system due to the RF communication protocol's lack of encryption, leaving data frames exposed. This flaw allows an attacker with a radio interception tool to capture sensitive information, such as the Key Fob ID and rolling code counters, transmitted in cleartext. The KE700 version is affected, and the vulnerability arises from a fundamental design flaw in the system's rolling code implementation, which does not secure transmissions, enabling potential brute-force attacks.

It is recommended to implement encryption for the entire transmission frame using a standard symmetric algorithm, such as AES-128. Additionally, the encrypted payload should include a Message Authentication Code (MAC) to prevent tampering or spoofing.
