CVE-2026-20895 is a high-severity flaw (CVSS 7.3) affecting ev2go.io. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized
