CVE-2025-27769

Physical access to services via charging cable

Published Mar 10, 2026 · Updated Mar 10, 2026

Improper access control in Siemens Heliox EV chargers allows physically proximate attackers to reach unauthorized services via a charging cable. Siemens identifies the charging-cable communication path as the locus but has not disclosed which services are exposed or how endpoint access control fails. Physical access to a charging connector is required, and Siemens does not identify the information available through the exposed services.
