Home Assistant是Home Assistant组织开源的一款智能家居自动化平台。 Home Assistant 2026.5.3之前版本存在授权问题漏洞，该漏洞源于Companion app将通过操作系统级路由机制传递的标签链接（NFC或QR）视为物理扫描，且未验证调用应用或提示用户，导致设备上任何不受信任的应用均可向Home Assistant转发任意标签，执行相关自动化，实现静默、无人值守的自动化执行。

Vulnerability Title
Home Assistant: Unconfirmed NFC/QR tag scans allow silent automation execution by untrusted callers
Source: CVE Program / CVE List V5
Vulnerability Description
Home Assistant is open source home automation software focused on local control and privacy. Prior to 2026.5.3, the Companion app treats tag links (NFC or QR) delivered through an OS-level routing mechanism as if they were physically scanned, without validating the calling app or prompting the user. As a result, any untrusted app on the device can forward an arbitrary tag to Home Assistant, causing it to execute the associated automation as though a legitimate user had scanned an authorized tag. This allows silent, unattended automation execution by untrusted local callers. This issue is fixed in version 2026.8.1.
