{"id":"CVE-2026-66060","state":"PUBLISHED","title":"Home Assistant: Unconfirmed NFC/QR tag scans allow silent automation execution by untrusted callers","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.
