Overview<\/strong><\/p>\n

The cybersecurity vulnerability identified as CVE-2025-26450 is a significant issue that affects all applications using the IInputMethodSessionWrapper.java. This vulnerability is highly critical because it could potentially allow an untrusted application to inject key and motion events to the default Input Method Editor (IME), leading to local privilege escalation without any need for additional execution privileges. A successful exploit could lead to system<\/a> compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-26450
\nSeverity: High (7.8 CVSS Score)
\nAttack Vector: Local
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Android OS | All versions<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability works by exploiting a missing permission check in the onInputEvent of IInputMethodSessionWrapper.java. This allows an attacker to use an untrusted application<\/a> to inject key and motion events to the default Input Method Editor (IME). This can lead to local escalation of privilege<\/a> with no additional execution privileges needed. User interaction is not needed for exploitation.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual code snippet that demonstrates how a malicious application might exploit this vulnerability:<\/p>\n

\/\/ Pseudocode to illustrate the exploit\npublic class MaliciousApp {\npublic static void injectKeyAndMotionEvents() {\nIInputMethodSessionWrapper wrapper = getWrapperInstance();\nKeyEvent keyEvent = createKeyEvent();\nMotionEvent motionEvent = createMotionEvent();\n\/\/ Injecting key and motion events to default IME\nwrapper.onInputEvent(keyEvent);\nwrapper.onInputEvent(motionEvent);\n}\n}<\/code><\/pre>\n
This code is not functional; it is only a conceptual representation of the potential exploit. The actual exploit might involve more complex techniques to inject malicious events into the default IME.<\/p>\n","protected":false},"excerpt":{"rendered":"
