CVE-2026-28766: CWE-306 in Gardyn Cloud API
CVE-2026-28766 is a critical vulnerability in the Gardyn Cloud API where a specific endpoint exposes all user account information for registered users without requiring any authentication. This lack of access control allows unauthenticated attackers to retrieve sensitive user data. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function). There is no official patch or remediation level provided yet, and no known exploits in the wild have been reported. The CVSS 4. 0 base score is 9. 2, indicating a critical severity due to network attack vector, no required privileges, and no user interaction needed.
AI Analysis
Technical Summary
This vulnerability in the Gardyn Cloud API involves an unauthenticated endpoint that leaks all user account information for registered users. The absence of authentication on this endpoint constitutes a critical security flaw (CWE-306), allowing attackers to access sensitive data remotely without any credentials. The CVSS 4.0 score of 9.2 reflects the high impact and ease of exploitation. No official remediation or patch has been documented, and the service is not cloud-hosted, so vendor-managed patching is not implied.
Potential Impact
An attacker can remotely access all user account information from the affected Gardyn Cloud API without authentication, potentially leading to significant privacy breaches and unauthorized data disclosure. The critical CVSS score underscores the severity of this exposure. No known exploits have been reported so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the vulnerable endpoint through network controls or API gateways if possible. Monitor for updates from Gardyn regarding patches or official mitigations.
