DescriptionGitHub Advisory

EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to use-after-free. This is triggered by EV plug-in/unplug and RFID/RemoteStart/OCPP authorization events (or delayed authorization response). Version 2026.2.0 contains a patch.

AnalysisAI

EVerest charging software stack versions prior to 2026.02.0 contain a data race condition leading to use-after-free memory corruption, triggered by EV plug-in/unplug events and authorization flows (RFID, RemoteStart, OCPP). Unauthenticated physical attackers with high complexity can exploit this to leak sensitive information or cause denial of service on affected charging infrastructure. …

Vulnerability AssessmentAI

Risk Assessment	CVSS 5.3 with attack vector Physical (AV:P) and high complexity (AC:H) indicates this is not a remote network attack; exploitation requires physical proximity to the charging station and precise timing of plug/authorization event sequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker with physical access to a charging station rapidly inserts and removes an EV plug while simultaneously submitting an RFID card read or RemoteStart authorization request. The timing causes a data race where the authorization handler deallocates the plug state structure while the plug event handler still references it, triggering a use-after-free condition that either crashes the charging controller (denial of service) or leaks heap memory containing authentication tokens or session data.
Remediation	Upgrade EVerest-core to version 2026.02.0 or later, which contains the patch addressing the data race condition (see vendor advisory at https://github.com/EVerest/EVerest/security/advisories/GHSA-vgmh-mmg3-22m6). … Detailed patch versions, workarounds, and compensating controls in full report.
