Published May 28, 2026 CVSS 4.0 · 8.6 High EPSS < 1% KEV · Not listed
Description
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.
