CVE-2026-27027Network attack vector

Credential disclosure via public web maps

Published Mar 6, 2026 · Updated Mar 6, 2026

Credential exposure in Everon OCPP Backends allows remote attackers to obtain charging station authentication identifiers from mapping platforms. Public web maps disclose the station identifiers used for charger authentication instead of keeping those identifiers secret. Possession of an exposed identifier is the access gate; CISA does not publish the affected map field, backend routine, or resulting operations.
