Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Locks the device (typically after inactivity) until re-authentication, addressing insufficient session expiration by preventing indefinite access.
Automatically terminating sessions after a defined period directly enforces session expiration, preventing indefinite session lifetimes that attackers can exploit.
Re-authentication after inactivity or time-based triggers prevents indefinite use of potentially hijacked or stale sessions.
Terminating sessions and network connections upon completion prevents insufficient session expiration.
Directly enforces termination of network sessions after inactivity or end-of-session, preventing indefinite session lifetime.
Consistent clocks across systems allow session expiration and timeout enforcement to function as intended in distributed environments.
When the non-persistent artifact is a session or connection, mandatory termination implements the missing expiration that CWE-613 describes.
Timed refresh of session-related information or on-demand generation plus deletion implements proper session expiration.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability in public-facing WebSocket backend enables exploitation of the service for initial access (T1190); predictable session IDs derived from station identifiers directly facilitate hijacking of preexisting remote service sessions to intercept commands or displace legitimate connections (T1563).
NVD 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.
Deeper analysisAI
CVE-2026-25711 is a vulnerability in the WebSocket backend used by charging station management systems, where session identifiers are derived from charging station identifiers. This design permits multiple endpoints to connect using the same session identifier, resulting in predictable session IDs. Consequently, the most recent connection can displace the legitimate charging station, hijacking or shadowing the session and intercepting backend commands intended for that station.
The vulnerability has a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity with network accessibility, low attack complexity, and no required privileges. Remote attackers can exploit it by connecting to the WebSocket backend with a known or predictable session identifier from a legitimate charging station. Successful exploitation enables unauthorized authentication as other users, session hijacking to receive commands, or denial-of-service by overwhelming the backend with valid session requests.
