Detailsinfo

A vulnerability classified as critical has been found in EV Energy (unknown version). This affects an unknown code block. The manipulation with an unknown input leads to a session expiration vulnerability. CWE is classifying the issue as CWE-613. According to WASC, "Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization." This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared by Khaled Sarieddine and Mohammad Ali Sayed. This vulnerability is uniquely identified as CVE-2026-26290 since 02/24/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/06/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
