CVE-2017-20181

Local file disclosure via unchecked content URI

Published Mar 6, 2023 · Updated Mar 5, 2025

Path traversal in hgzojer Vocable Trainer 1.0 through 1.3 allows local users to read files outside the app cache via a crafted content URI. VocableTrainerProvider.openFile() joins the URI's final path segment to the cache directory and opens the result without checking its canonical path. Local users able to invoke the content provider can traverse into files readable within Vocable Trainer's application sandbox.
