What is CVE-2026-29044?
CVE-2026-29044 is a medium-severity vulnerability in everest-core, published on 26 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
EVerest is an EV charging software stack. Prior to version 2026.02.0, when WithdrawAuthorization is processed before the TransactionStarted event, AuthHandler determines `transaction_active=false` and only calls `withdraw_authorization_callback`. This path ultimately calls `Charger::deauthorize()`, but no actual stop (StopTransaction) occurs in the Charging state. As a result, authorization withdrawal can be defeated by timing, allowing charging to continue. Version 2026.02.0 contains a patch.
Weakness: CWE-863
