Security readout for executives and security teams
Plain-English summary
CVE-2026-26305 affects Mobility46 mobility46.se. Its WebSocket API does not sufficiently limit repeated authentication attempts. An attacker could overload authentication handling, disrupt legitimate charger telemetry, or attempt password guessing. This is most urgent for organizations relying on Mobility46-connected chargers where telemetry availability affects operations.
Executive priority
Prioritize assessment if Mobility46 supports revenue-generating or safety-relevant charging operations. The main business risk is charger telemetry disruption and possible unauthorized access attempts. Treat as high priority until vendor remediation and exposure are confirmed.
Technical view
The issue is CWE-307: improper restriction of excessive authentication attempts in the WebSocket API. The CVSS 4.0 score is 8.7, with network attack vector, low complexity, no privileges, and no user interaction. Reported impact is high availability loss; confidentiality and integrity impacts are not scored in the vector.
Likely exposure
Exposure is likely where Mobility46 mobility46.se WebSocket authentication endpoints are reachable by untrusted networks or the internet. The source bundle lists Mobility46 mobility46.se, all versions, but also shows defaultStatus as unaffected; confirm status directly with CISA and Mobility46.
Exploitation context
The sources describe possible denial of service through suppressed or mis-routed charger telemetry, and brute-force authentication attempts. No provided source states active exploitation, and the CVE is not listed as KEV in the bundle.
Researcher notes
Evidence is limited to the CVE record, CISA advisory references, and CSAF reference. No exploit availability, active exploitation, or patch details are provided in the bundle. The affected-version statement should be validated because the bundle simultaneously lists all versions and a default unaffected status.
Mitigation direction
- Check Mobility46 and CISA advisory guidance for confirmed remediation or configuration instructions.
- Limit WebSocket API exposure to trusted networks where operationally possible.
- Monitor for excessive authentication attempts and telemetry disruption indicators.
- Use strong, unique credentials for accounts accessing the service.
- Contact Mobility46 support for affected-version clarification and remediation status.
Validation and detection
- Inventory Mobility46 mobility46.se deployments and connected charger telemetry dependencies.
- Confirm whether WebSocket authentication endpoints are internet-accessible.
- Review authentication logs for abnormal repeated failures or traffic spikes.
- Review telemetry logs for unexplained suppression, gaps, or misrouting.
- Verify current vendor guidance against deployed versions and configurations.

Improper Restriction of Excessive Authentication Attempts
Improper Restriction of Excessive Authentication Attempts represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
