CVE-2026-22093Network attack vector

Traffic interception and manipulation via unvalidated certificates

Published Jul 13, 2026 · Updated Jul 13, 2026

Improper certificate validation in EVbee Service before 1.4.7.10 allows man-in-the-middle attackers to intercept app-server traffic. The Android app accepts any presented server certificate without validation and applies RC4 with a hardcoded key to application data. Network-path access is required; successful interception exposes and permits modification of charger communications, including charging-station access codes.
