Summary
CVE-2026-27652 is a medium-severity Insufficient Session Expiration (CWE-613) vulnerability in Cloudcharge Cloudcharge.Se. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 24th 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-2026-27652 is a vulnerability in the WebSocket backend for charging station management systems, where charging station identifiers are used to uniquely associate sessions, but the implementation permits multiple endpoints to connect using the same session identifier. This results in predictable session identifiers, facilitating session hijacking or shadowing, in which the most recent connection displaces the legitimate charging station and receives backend commands intended for it. The issue is rated with 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 maps to CWE-613.
Attackers with network access can exploit this vulnerability without privileges or user interaction. An unauthorized user may authenticate as other users by hijacking sessions, gaining limited access to confidential information, modifying data, or executing commands on behalf of legitimate charging stations. Additionally, a malicious actor can cause a denial-of-service condition by overwhelming the backend with valid session requests, displacing legitimate connections.
CISA has published ICS Advisory ICSA-26-057-03 detailing the vulnerability, available at https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-03, along with a corresponding CSAF file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-03.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.
