CVE-2025-68139

Session persistence via nonterminating failed V2G responses

Published Jan 21, 2026 · Updated Jan 21, 2026

Session fixation in EVerest Core 2025.12.1 and earlier allows physically proximate attackers to preserve failed V2G sessions. The terminate_connection_on_failed_response setting defaults to false, so failed response codes are logged without resetting or terminating the V2G connection. Access to the charging interface is required, and the retained session is only a stepping stone for exploiting another weakness; no standalone data access or service interruption is reported.
