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?
Public-facing WebSocket flaw directly enables exploitation via T1190; predictable/reusable session IDs allow takeover of remote service sessions (T1563) for impersonation and command access.
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-2026-24912 affects the WebSocket backend in charging station management systems, where sessions are uniquely associated using charging station identifiers. However, the implementation permits multiple endpoints to connect with the same session identifier, resulting in predictable identifiers that enable session hijacking or shadowing. In this scenario, the most recent connection displaces the legitimate charging station, allowing it to receive backend commands intended for that station. The vulnerability, classified under CWE-613 (Insufficient Session Expiration), carries 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) and was published on 2026-03-06.
Network-accessible attackers require no privileges or user interaction to exploit this issue. By using a known or predictable session identifier, an unauthorized party can hijack a session, impersonate a legitimate charging station, and access commands or data meant for it, potentially enabling unauthorized authentication as other users. Alternatively, a malicious actor can cause a denial-of-service condition by overwhelming the backend with multiple valid session requests.
CISA has issued ICS Advisory ICSA-26-062-07 detailing the vulnerability, available at https://www.cisa.gov/news-events/ics-advisories/icsa-26-062-07, along with a corresponding CSAF JSON file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-062-07.json.
