ZDI-26-560: (Pwn2Own) Home Assistant Green go2rtc Command Injection Remote Code Execution Vulnerability
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Home Assistant Green. An attacker must first obtain the ability to access the device's localhost interface. The ZDI has assigned a CVSS rating of 7.5.
AI Analysis
Technical Summary
The vulnerability in Home Assistant Green involves the go2rtc process improperly validating user-supplied strings before using them in system calls, enabling command injection. An attacker must first gain access to the device's localhost interface, which is a prerequisite for exploitation. Successful exploitation allows arbitrary code execution with root privileges. The issue was reported to the vendor on November 5, 2025, and publicly disclosed on August 12, 2026. The fix is available in go2rtc version 1.9.14 and the related Home Assistant update.
Potential Impact
Exploitation allows an attacker with network adjacency and localhost access to execute arbitrary code as root on the affected device. This can lead to full system compromise, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
A fix is available and has been released in go2rtc version 1.9.14 and the corresponding Home Assistant update. Users should upgrade to these versions to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
