CVE-2026-107058 Details
Description
An issue in Shelter versionCode 445 allows attackers to register their own auth_key and execute a takeover of another user's binder service API and preference state.
A vulnerability in the Shelter app, specifically in version 445, allows attackers to register their own authentication keys. This unauthorized key registration can lead to a takeover of another user's binder service API and preference state. The issue arises because the exported device-admin activity in Shelter accepts HMAC keys from the caller's Intent without proper validation, enabling the first caller to manipulate the authentication process.
As of now, no fix has been released for this vulnerability. However, it is recommended to add an 'android:permission' to the affected component or set 'android:exported' to 'false' to prevent external access.
