DescriptionGitHub Advisory

EVerest is an EV charging software stack. Versions prior to 2026.02.0 have an out-of-bounds access (std::vector) that leads to possible remote crash/memory corruption. This is because the CSMS sends UpdateAllowedEnergyTransferModes over the network. Version 2026.2.0 contains a patch.

AnalysisAI

Out-of-bounds vector access in EVerest EV charging software (everest-core versions before 2026.02.0) enables remote unauthenticated attackers to crash the charging station software or corrupt memory by sending crafted UpdateAllowedEnergyTransferModes messages from a Charging Station Management System (CSMS). CVSS 7.5 severity reflects network-accessible denial of service with high availability impact. SSVC assessment indicates no current exploitation and non-automatable attack; no public exploit identified at time of analysis.

Technical ContextAI

EVerest is an open-source software stack for electric vehicle charging infrastructure that communicates with Charging Station Management Systems (CSMS) over OCPP (Open Charge Point Protocol). The vulnerability stems from CWE-125 (Out-of-bounds Read) occurring during processing of UpdateAllowedEnergyTransferModes messages, which can trigger std::vector boundary violations. Affected product is everest-core (CPE: cpe:2.3:a:everest:everest-core:*:*:*:*:*:*:*:*) across all versions prior to 2026.02.0. The network-facing nature of CSMS communication expands attack surface to any entity capable of sending OCPP messages to the charging station software, making this a critical infrastructure vulnerability in EV charging deployments.

RemediationAI

Upgrade everest-core to version 2026.02.0 or later, which contains the vendor-released patch for this vulnerability as documented in the GitHub security advisory at https://github.com/EVerest/EVerest/security/advisories/GHSA-vw95-6jj7-3fv9. Until patching is feasible, implement network segmentation to restrict CSMS communication to authenticated and trusted management systems only, deploy intrusion detection rules to monitor for malformed UpdateAllowedEnergyTransferModes messages, and consider rate-limiting OCPP message processing. Organizations should validate that update deployment does not disrupt charging operations by testing in non-production environments first. Monitor EVerest project releases and the referenced GitHub advisory for additional security guidance specific to EV charging infrastructure hardening.
