2.12.2026
CVE-2026-28767 describes an authentication bypass vulnerability within the Gardyn Cloud API. This flaw allows unauthorized access to administrative notifications, potentially exposing sensitive information or enabling malicious actions. The vulnerability impacts versions 0.0.0 through 2.12.2026 of the API, and a patch is available in version 2.12.2026.
The primary impact of CVE-2026-28767 is the potential for unauthorized access to administrative notifications within the Gardyn Cloud API. An attacker exploiting this vulnerability could gain insights into system operations, user activity, or other sensitive data managed through the API. While the direct impact might seem limited to notification access, this could be a stepping stone for further attacks, such as gaining access to user data or manipulating system configurations. The blast radius depends on the sensitivity of the information contained within these administrative notifications.
CVE-2026-28767 was publicly disclosed on April 3, 2026. There is currently no indication of active exploitation or a public proof-of-concept. The vulnerability is not listed on the CISA KEV catalog at the time of this writing. Given the relatively straightforward nature of the bypass, it's possible that opportunistic exploitation could occur.
Gardyn users and organizations relying on the Gardyn Cloud API for managing their smart gardening systems are at risk. This includes both individual users and larger commercial deployments. Systems with older, unpatched versions of the API are particularly vulnerable.
