CVE-2026-27770: Medium Vulnerability in Charging Station Authentication

CVE-2026-27770 is classified as a medium-severity vulnerability, with a CVSS score of 6.9. This vulnerability allows charging station authentication identifiers to be publicly accessible via web-based mapping platforms, potentially exposing sensitive information. The low attack complexity and lack of required privileges or user interaction mean that the risk to organizations is significant.

As this vulnerability remains under analysis, the urgency for organizations to address it is moderate. Given the nature of the exposure, organizations should prepare to implement corrective measures promptly to protect their systems and data.

The vulnerability was published on March 6, 2026, and is currently awaiting further analysis. Organizations should closely monitor updates regarding this vulnerability to ensure timely remediation.

Risk to organizations includes potential unauthorized access to sensitive data associated with charging stations. Attackers may leverage this information for malicious purposes, therefore organizations should prioritize patching immediately.

Vulnerability Details

According to the official description, charging station authentication identifiers are publicly accessible via web-based mapping platforms. This vulnerability falls under CWE-522, which refers to exposure of sensitive information through an incorrect access control.

The CVSS 4.0 score is 6.9, denoting a medium severity. The attack vector is categorized as network, with a low attack complexity, requiring no privileges or user interaction. The confidentiality and integrity impacts are both rated as low, while availability impact is assessed as none.

Technical Analysis

The root cause of this vulnerability stems from inadequate access controls that allow sensitive authentication identifiers to be publicly accessible. The attack vector is through network access, which is relatively low in complexity, meaning that an attacker can easily exploit this without advanced technical skills.

Since there are no privileges required or user interactions necessary to exploit this vulnerability, the potential for unauthorized access is heightened. The low confidentiality and integrity impacts indicate that while the information may not be critical, its exposure could still be leveraged for further attacks.

Risk & Impact Analysis

The real-world risk associated with CVE-2026-27770 lies in the potential for unauthorized access to charging station systems, which could lead to further attacks or data breaches. Given the growing reliance on electric vehicle infrastructure, the blast radius of this vulnerability could extend widely, affecting multiple users and operators.

Organizations must understand the urgency of addressing this vulnerability. With a CVSS score of 6.9, it is essential to incorporate this into the priority patch cycle to prevent any possible exploitation or data compromise.

Affected Versions

Currently, there are no specific versions listed as affected. Organizations are advised to consider all versions prior to vendor patch until further information is available.

Mitigation & Remediation

Organizations should monitor the situation closely and implement any patches or updates as soon as they become available. Configuration hardening and network controls may also help mitigate risks associated with this vulnerability.
