Summary
CVE-2026-24912 is a medium-severity Insufficient Session Expiration (CWE-613) vulnerability in Epower Epower.Ie. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-12 (Session Termination) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Credential lifecycle management directly includes enforcing session expiration to prevent reuse.
Authorization policy enforcement and review covers terminating stale sessions to limit access scope.
Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.
