The Cybersecurity and Infrastructure Security Agency (CISA) has published advisory ICSA-26-274-02 disclosing four vulnerabilities in Monta monta.app, a widely used electric vehicle charging station management platform. The flaws span missing authentication, lack of rate limiting on WebSocket endpoints, predictable session identifiers, and insufficiently protected credentials. All versions of the software are affected. While no active exploitation has been confirmed, the CVSS scores range from 7.5 to 9.4, classifying three as Critical and one as High severity. The advisory urges operators to enable OCPP 1.6 Security Profile 2 and apply interim mitigations such as rate limiting.
