CVE-2026-32663Network attack vector

Unauthenticated session hijacking via duplicate identifiers

Published Mar 20, 2026 · Updated Mar 20, 2026

Session expiration failure in all versions of IGL-Technologies eParking.fi allows remote attackers to hijack OCPP WebSocket sessions. The backend treats a charging-station identifier as the unique session key but accepts a second endpoint with the same predictable identifier, replacing the legitimate connection and routing its commands to the newcomer. An unencrypted OCPP deployment and a valid or discovered station identifier expose unauthorized command receipt and service interruption; encrypted OCPP and eTolppa deployments are not affected.
