CVE-2026-107034 Details
Description
Insecure permissions in LeafPad / Leaf Note v1.21 (versionCode 21) allows unauthorized attackers to arbitrarily read another user's note data.
A vulnerability in LeafPad version 1.21 (versionCode 21) for Android exists due to insecure permissions. The exported, permission-less 'NoteEditActivity' can be invoked by any app, allowing unauthorized access to another user's note data. The activity reads 'Intent.EXTRA_TEXT' and saves it as a new note in the user's database, bypassing any user interaction or permissions. This issue arises from improper export of Android application components, enabling a trust boundary crossing from an untrusted app to the victim app's data.
As of now, no fix has been released. However, it is recommended to add a permission to the exported activity or to set 'android:exported' to 'false' when external access is not intended.
