What is CVE-2025-12080?
CVE-2025-12080 is a medium-severity missing authorization vulnerability in Google WearOS, published on 27 Oct 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
On Wear OS devices, when Google Messages is configured as the default SMS/MMS/RCS application, the handling of ACTION_SENDTO intents utilizing the sms:, smsto:, mms:, and mmsto: Uniform Resource Identifier (URI) schemes is incorrectly implemented.
Due to this misconfiguration, an attacker capable of invoking an Android intent can exploit this vulnerability to send messages on the user’s behalf to arbitrary receivers without requiring any further user interaction or specific permissions. This allows for the silent and unauthorized transmission of messages from a compromised Wear OS device.
Weakness: CWE-345
