Security readout for executives and security teams
Plain-English summary
CVE-2026-27647 affects Mobility46 mobility46.se. The backend can accept multiple WebSocket connections using the same charging station identifier, letting a new connection displace the legitimate station. Business impact may include unauthorized command receipt, session hijacking or shadowing, and service disruption. No active exploitation is indicated in the provided sources.
Executive priority
Treat this as high priority for environments operating Mobility46-connected charging infrastructure. The issue could affect trust in station-to-backend communications and service availability. Prioritize exposure confirmation, vendor engagement, and monitoring while awaiting confirmed remediation details.
Technical view
The issue is classified as CWE-613, insufficient session expiration. Charging station identifiers are used to associate WebSocket sessions, but duplicate use is allowed and identifiers are described as predictable. CVSS is 7.3 high, network exploitable, low complexity, no privileges or user interaction required, with limited confidentiality, integrity, and availability impact.
Likely exposure
Organizations using Mobility46 mobility46.se, especially connected charging station environments with reachable WebSocket backends, should assume potential exposure. The source bundle lists all versions as affected, but also includes an inconsistent default status field, so confirm scope with Mobility46 or CISA guidance.
Exploitation context
The provided sources describe possible session hijacking, shadowing, and denial of service through valid session requests. CISA KEV status is false in the bundle, and no cited source states active exploitation. Public exploit availability is not established by the provided evidence.
Researcher notes
Evidence is limited to the CVE description, CISA advisory reference, CSAF reference, and vendor contact link. Do not assume exploit maturity, patch availability, or affected deployment architecture beyond those sources. The affected-version data contains an apparent inconsistency that should be verified before broad scoping decisions.
Mitigation direction
- Check Mobility46 and CISA guidance for fixed versions or vendor-recommended mitigations.
- Contact Mobility46 support if no remediation notice is available.
- Reduce unnecessary exposure of the WebSocket backend where operationally feasible.
- Monitor for duplicate charging station identifiers or unexpected session replacement events.
- Prioritize controls that prevent unauthenticated access to backend communication paths.
Validation and detection
- Inventory Mobility46 mobility46.se deployments and related charging station integrations.
- Confirm whether affected environments use WebSocket sessions tied to charging station identifiers.
- Review logs for duplicate identifiers, frequent reconnects, or unexpected station displacement.
- Verify vendor advisory status and whether a fixed release is available.
- Document compensating controls and residual exposure until vendor remediation is confirmed.

Insufficient Session Expiration
Insufficient Session Expiration represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
