Version 2026.02.0 contains a patch that corrects the logic and ensures that a withdrawal of authorization stops the charger.", "description_and_impact": "EVerest, an electric\u2011vehicle charging stack, has a flaw in which processing a WithdrawAuthorization request before a TransactionStarted event causes the system to mark the transaction as inactive but fails to stop the charger. As a result, the charger can keep supplying power even after the authorization has been withdrawn, potentially leading to unintended energy draw and safety risks.", "risk_and_exploitability": "The CVSS score of 5 indicates a medium severity. EPSS is less than 1%, suggesting that exploitation is likely rare. The vulnerability is not listed in CISA\u2019s KEV catalog. Exploitation would require an attacker to send a WithdrawAuthorization request prior to the TransactionStarted event, likely through the network interface that controls charging commands. No direct remote code execution is possible; the risk is limited to continued charging beyond the expected authorization period."}}}}, "created": "2026-03-27T08:33:47.535736+00:00", "updated": "2026-03-31T20:08:49.386547+00:00", "vendors": ["everest", "everest$PRODUCT$everest-core"]}
