CVE-2026-27773 is a vulnerability identified in all versions of SWITCH EV's swtchenergy.com platform, where charging station authentication identifiers are exposed publicly via web-based mapping platforms. This exposure corresponds to CWE-522, which denotes insufficient protection of credentials, specifically authentication identifiers in this case. The vulnerability allows an attacker to access authentication identifiers without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact primarily affects confidentiality and integrity, as unauthorized parties could potentially use these identifiers to impersonate charging stations or manipulate authentication processes, potentially leading to unauthorized charging sessions or data manipulation. However, availability is not impacted. The vulnerability is network exploitable and does not require authentication, increasing the risk of exploitation. Despite no known exploits in the wild, the public accessibility of these identifiers on mapping platforms presents a significant risk vector. The lack of patch links suggests that remediation may require vendor intervention or configuration changes to restrict access to sensitive data. This vulnerability highlights the importance of securing authentication credentials and limiting their exposure, especially in IoT and critical infrastructure contexts such as electric vehicle charging networks.

The exposure of charging station authentication identifiers can lead to unauthorized access and misuse of charging infrastructure. Attackers could impersonate legitimate charging stations, potentially causing fraudulent charging sessions, financial losses, or disruption of service integrity. Confidentiality breaches may also expose user or operational data linked to these identifiers. While availability is not directly affected, integrity compromises could undermine trust in the charging network and lead to operational disruptions. Organizations worldwide that deploy SWITCH EV charging stations or rely on swtchenergy.com services face risks of unauthorized access and potential manipulation of charging sessions. This could also have reputational impacts and regulatory consequences, especially in regions with strict data protection laws. The vulnerability could be leveraged in broader attack campaigns targeting electric vehicle infrastructure, which is critical for sustainable transportation and energy management.

To mitigate this vulnerability, organizations should immediately audit and restrict access to charging station authentication identifiers on all web-based mapping platforms. SWITCH EV should implement access controls and authentication mechanisms to prevent public exposure of sensitive credentials. Employing encryption or tokenization for authentication identifiers can reduce the risk of unauthorized use. Monitoring and logging access to these identifiers should be enhanced to detect suspicious activities promptly. Organizations should coordinate with SWITCH EV for patches or configuration updates once available. Additionally, segregating the mapping platform from sensitive authentication data and applying the principle of least privilege in data exposure are critical. Regular security assessments and penetration testing focused on credential exposure can help identify and remediate similar issues proactively. Finally, educating operational staff about the risks of credential exposure and best practices for secure configuration is essential.
