CVE-2026-27652
CWE-613Published: February 27, 2026· Updated: Mar 5, 2026
Official Description
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.
Technical Analysis
CVE-2026-27652 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in availability disruption (denial of service), with a CVSS base score of 7.5.
