CVE-2018-9375Public exploit

Dictionary disclosure and modification via late authorization

Published Jan 17, 2025 · Updated Mar 13, 2025

Authorization bypass in Android 6.0 through 8.1 allows local users to read, update, or delete personal-dictionary entries. UserDictionaryProvider's update() and delete() methods modify exported-provider database rows before canCallerAccessUserDictionary() rejects unauthorized callers. Any locally installed app can invoke the provider without permission or user interaction; timed conditional updates can indirectly disclose entries, while direct calls can alter or erase them.
