Technical details
A configuration weakness (CWE-1188) in the XCharge C6 remote management service allows an authenticated session to be established over the Power Line Communication (PLC) or signaling channel intended for vehicle-to-charger communication. The service is improperly exposed on the physical charging interface and utilizes a default administrative credential. An attacker can connect a malicious device to the charging connector to access the management interface and gain full administrative rights. XCharge has reportedly deployed a firmware update to address this issue as of May 22, 2026.
