By Sai Kiran Pandrala. Last verified: 2026-05-25.

CVE-2026-27652 is a sibling vulnerability in the same vendor advisory as CVE-2026-20733. Apply the same patched build and you close both. The technical detail below is what differs.

What's different about CVE-2026-27652?

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 users to authenticate as other users or enable a

malicious actor to cause a denial-of-service condition by overwhelming

the backend with valid session requests.
