Leafpad: Exported Android component allows writing notes without permission
Leafpad for Android, version 1.21, exports an activity that needs no permission. Any app installed on the same device can send text to it, and the text is saved as a new note in the app's database without user interaction. The reporter demonstrated this with a test app, and the injected notes persisted after a restart. The NVD score of 9.1 assumes a network attack, while another source rates the attack as local, so the actual exposure is still disputed.
