Local information disclosure via URI permission bypass
Published Jan 22, 2021 · Updated Aug 4, 2024
Information disclosure in the Android 11 Framework allows local users to read protected data through a URI permission bypass. checkGrantUriPermission in UriGrantsManagerService.java incorrectly approves URI access without enforcing the intended permission. Exploitation requires local low-privileged access but no user interaction, and Google has not identified the protected data exposed.
