Keyboard denial of service via exposed provider
Published Jun 9, 2023 · Updated Jan 28, 2025
Improper authorization in Facemoji Emoji Keyboard 2.9.1.2 allows attackers to disable keyboard input through a crafted Android intent. An exported content provider accepts writes from unauthorized applications and stores attacker-controlled key_enable_subtype values in profile_enable_subtype.xml. A user must install or invoke a malicious local app; corrupting both documented preference keys prevents the keyboard from opening and triggers repeated errors.
