Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-12080 involves a misconfigured intent handler in Google Messages on Wear OS. This vulnerability allows attackers with the ability to invoke intents to send messages on behalf of the user without requiring confirmation or explicit permission. The issue stems from the incorrect handling of ACTION_SENDTO intents using the sms:, smsto:, mms:, and mmsto: URI schemes when Google Messages is the default SMS/MMS/RCS app. An attacker could exploit this by distributing an app that appears legitimate and silently sends messages to arbitrary targets without needing user permissions. This could lead to security and financial threats, as the exploitation is stealthy and difficult for users to detect.

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.
