CVE-2026-2539 is a medium-severity vulnerability rated 5.7/10 on the CVSS scale. The RF communication protocol in the Micca KE700 car alarm system does not encrypt its data frames. An attacker with a radio interception tool (e.g., SDR) can capture the random number and counters transmitted in cleartext, which is sensitive information required for authentication.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
