Critical Authentication Bypass in Gardyn Home IoT Firmware CVE-2026-13768
CVE-2026-13768 is a critical vulnerability in Gardyn Home IoT firmware resulting from CWE-798 (Use of Hardcoded Credentials). This flaw allows unauthorized remote attackers to bypass authentication mechanisms and gain full administrative access to the device. Exploitation enables lateral movement within local area networks (LAN) and provides direct control over environmental actuators, including water and nutrient delivery systems. The vulnerability was identified through firmware reverse engineering and validated via a Proof-of-Concept (PoC). Immediate remediation requires deploying the latest firmware patch provided by Gardyn Engineering to remove the static credentials.
