CVE-2026-27767 describes a critical vulnerability in swtchenergy.com's WebSocket endpoints. The lack of authentication allows attackers to impersonate charging stations and manipulate data intended for the backend systems. This vulnerability affects all versions of the product and poses a significant risk to charging infrastructure. Mitigation strategies involve implementing robust authentication and access controls.
The primary impact of CVE-2026-27767 is the potential for unauthorized control of charging infrastructure. An attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier and issue commands as if they were a legitimate charger. This could involve manipulating charging rates, disconnecting vehicles prematurely, or even causing physical damage to the charging equipment. Furthermore, the attacker can intercept and modify data sent to the backend, potentially corrupting charging network data and leading to inaccurate billing or reporting. The blast radius extends to the entire charging network managed by swtchenergy.com, as a single compromised station could be used to launch attacks against others.
CVE-2026-27767 was publicly disclosed on 2026-02-26. The CVSS score of 9.4 (CRITICAL) indicates a high probability of exploitation. There are currently no known public proof-of-concept exploits, but the ease of exploitation due to the lack of authentication suggests that it could be quickly developed. The vulnerability is not currently listed on CISA KEV, but given its criticality, it may be added in the future. Active campaigns targeting charging infrastructure are a growing concern, making this vulnerability a high priority for remediation.
Organizations utilizing swtchenergy.com for managing their charging infrastructure are at risk. This includes electric vehicle charging network operators, fleet management companies, and businesses with on-site charging stations. Specifically, deployments relying on default configurations or lacking robust network segmentation are particularly vulnerable.

The immediate mitigation for CVE-2026-27767 is to implement robust authentication mechanisms on the WebSocket endpoints. This should involve verifying the identity of each charging station before allowing it to send or receive OCPP commands. As an interim measure, a Web Application Firewall (WAF) or proxy can be configured to restrict access to the WebSocket endpoint based on known or suspicious IP addresses or charging station identifiers. Additionally, carefully review and audit all OCPP commands being processed to detect any anomalies or unauthorized activity. After implementing authentication, confirm by attempting to connect to the WebSocket endpoint without proper credentials and verifying that access is denied.
OCPP WebSocket एंडपॉइंट्स के लिए मजबूत प्रमाणीकरण तंत्र लागू करें। सुनिश्चित करें कि प्रत्येक चार्जिंग स्टेशन को कमांड भेजने या प्राप्त करने की अनुमति देने से पहले ठीक से प्रमाणित किया गया है। चार्जिंग स्टेशनों की पहचान को सत्यापित करने के लिए डिजिटल प्रमाणपत्र या प्रमाणीकरण टोकन का उपयोग करने पर विचार करें।
