EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 90% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A configuration weakness in the device’s remote management service allows an authenticated session to be established over a communication channel intended solely for vehicle-charger signaling. The service is accessible on interfaces exposed through the charging connector, and it accepts a default administrative credential. A malicious device physically connected to the charging interface could leverage this misconfiguration to obtain full administrative access.
